# What is tangential lighting?

# What is light?

Light is a form of energy which gives a sensation of sight to eyes. It enables the eyes to see objects by the light the objects reflect or shadow. Light is a part of the electromagnetic spectrum. Some restrict "light" to what humans can detect with our eyes but many scientists simply use the word… light to mean any and all forms of electromagnetic radiation. To refer to light we can see, they often use the adjective "visible". Electromagnetic radiation is particle-waves. It possesses properties of both particles and waves. It has both a vibrating electric field and a magnetic field, each at right angles to the other and at right angles to its direction of travel. It is always travelling at a speed of roughly 2.998 x 10 8 metres/sec. Experiments with the photoelectric effect shows energy is transferred between atoms in discreet packets of energy suggesting a particle nature. In any case, "waves" and "particles" are only abstractions we use to visualise what we can't imagine because it is outside of our normal frame of reference. (*Light travels through transparent materials at a slower rate of speed, according to the material's refractive index .) Light is a visible energy given out by the sun, a light bub ect ( Full Answer )

# What tangentially related industries might impact the power tool industry?

# What state in the US has the greatest tangential speed as Earth rotates around its axis?

Hawaii, because it is closest to the equator therefore covering more distance in the same amount of time, so its faster!

# If you double the radius how will that affect tangential velocity?

Tangential velocity .
Your question leaves a lot to the imagination. One can only assume that you are talking about an object in circular motion, and you wish to know how doubling the radius of the orbit will change the linear -- or tangential -- speed of the object..
The trouble is, we don't kn…ow the angular velocity of either condition, so let's assume there is no difference. The following model illustrates..
Imagine you have a rope two meters long with a handle on one end, a ball on the other, and another ball located directly in between. Now, imagine yourself swinging the rope overhead so that the balls trace a circular path..
Both balls will have the same angular velocity, but the outside ball is moving much faster, because it has a greater distance to cover. How much greater? Well, since the circumference of a circle is proportional to the square of the radius, doubling the radius quadruples the circumference, so the outside ball must travel four times faster to keep up with the inside ball.

# What is the difference between tangential and radial acceleration?

Answer.
Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation..
Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.

# Distinguish between tangential speed and rotational speed?

Tangential speed is how fast a point on a circular object is moving at a certain distance from the center whereas rotational speed is how many degrees (or radians) a point on the circle goes through in a period of time. Every point on a circle has the same rotational speed. The further out you go… from the center, the higher the tangential speed is. ( Full Answer )

# What is tangential speed?

Linear speed is the distance traveled per unit of time, while tangential speed (or tangential velocity) is the linear speed of something moving along a circular path. [5] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point …nearer the center. Traveling a greater distance in the same time means a greater speed, and so linear speed is greater on the outer edge of a rotating object than it is closer to the axis. This speed along a circular path is known as tangential speed because the direction of motion is tangentto the circumference of the circle. For circular motion, the terms linear speed and tangential speed are used interchangeably, and both use units of m/s, km/h, and others. Rotational speed (or angular speed ) involves the number of revolutions per unit of time. All parts of a rigid merry-go-round or turntable turn about the axis of rotation in the same amount of time. Thus, all parts share the same rate of rotation, or the same number of rotations or revolutions per unit of time. It is common to express rotational rates in revolutions per minute (RPM) or in terms of the number of "radians" turned in a unit of time. There are little more than 6 radians in a full rotation (2Ï radians exactly). When a direction is assigned to rotational speed, it is known as rotational velocity or angular velocity. Rotational velocity is a vector whose magnitude is the rotational speed. Tangential speed and rotational speed are related: the greater the RPM's, the larger the speed in meters per second. Tangential speed is directly proportional to rotational speed at any fixed distance from the axis of rotation. [6] However, tangential speed, unlike rotational speed, depends on radial distance (the distance from the axis). For a platform rotating with a fixed rotational speed, the tangential speed in the center is zero. Towards the edge of the platform the tangential speed increases proportional to the distance from the axis. [7] In equation form:.
where v is tangential speed and Ï (Greek letter omega) is rotational speed. One moves faster if the rate of rotation increases (a larger value for Ï), and one also moves faster if movement farther from the axis occurs (a larger value for r ). Move twice as far from the rotational axis at the center and you move twice as fast. Move out three times as far and you have three times as much tangential speed. In any kind of rotating system, tangential speed depends on how far you are from the axis of rotation. When proper units are used for tangential speed v , rotational speed Ï, and radial distance r , the direct proportion of v to both r and Ï becomes the exact equation.
Thus, tangential speed will be directly proportional to r when all parts of a system simultaneously have the same Ï, as for a wheel, disk, or rigid wand. (The direct proportionality of v to r is not valid for planets, because planets have different rotational speeds). ( Full Answer )

# How do you use the word tangential in a sentence?

# What are the tangential and normal components of acceleration?

Well if you are familiar with calculus the projection of acceleration vector a(t)on to the Tangent unit vector T(t), that is tangential acceleration. While the projection of acceleration vector a(t) on to the normal vector is the normal acceleration vector. Therefore we know that acceleration is on… the same plane as T(t) and N(t). So component of acceleration for tangent vector is (v dot a)/ magnitude of v component of acceleration for normal vector is sqrt((magnitude of acceleration)^2 - (component of acceleration for tangent vector)^2) sorry i can't explain it to you more cause I don't have mathematical symbols to work with ( Full Answer )

# Relationship between tangential speed and distance from the center of rotational axis?

# What is a tangentially fired boiler?

A tangentially fired boiler has between 4 and 8 burners, placed in the corners of the boiler. These are sometimes angled vertically to maximize impingement of the flames. They are fired into the center of the boiler, not directly into the center, but at the wall to adjacent to them. This causes the …flames to swirl inside of the boiler, causing an even distribution of flame throughout the boiler. This is shown pretty well here: http://www.alstom.com/power/coal-oil/utility-boilers/firing-systems This website also has a lot more detail than previously provided. ( Full Answer )

# Why is the tangential speed of the top of a rotating wheel twice the translational speed at the center?

Quick Background: This question has baffled me for a while, but when I heard a friend of mine saying that police radar detectors can double your speed it started to make sense to me. Because when I hear physics-related facts in everyday terms they sometimes make more sense. The answer (with minimal… math) is: It all depends on the relative measurement reference point. Wheels spin, but when you put it against something, like the ground, then they start to push against each other. If your wheels are not slipping, or sliding, then they are in contact with the ground. This seems obvious, but when you assign a relative speed to two items in contact (with no slippage, or slideage [my new made-up word of the day]), then their speed relative to each other, is ZERO (pick whatever units you want). Zero mph Zero kph Zero you pick it This is interesting because the vehicle is still moving, relative to the ground. If the speed of the vehicle is 30 mph, then the axle of the vehicle is shooting down the road (hopefully with the rest of the car attached) at 30 mph. The top of the wheel, relative to the road, is double the axle speed (60 mph), so that it can average out with the 0mph at the ground/tire touch poing. I just came up with the idea, and I'm sure I'm not the first, that a wheel in motion, while contacting a surface (like the ground), is like a lever. The lever is pulling the vehicle in a direction. The top of the lever is moving, and in this case, the bottm is not (assuming no slippage). At the center of the lever is the car axle. See the wheel as a lever that pushes the axle forward and all will make sense. It's pretty cool. ( Full Answer )

# How does the tangential velocity of a planet relate to it orbiting around the sun?

The tangential velocity is equal to the circumference of the orbit divided by the time taken to go round once. For the Earth that is 2pi time 149.6 million kilometres divided by 365.25 days, which comes to 2.57 million km per day or 30 km/sec.

# Relationship between tangential speed and distance from the center of r?

tangential speed is directly proportional to rotational speed at nay fixed distance from the axis of rotation

# A model airplane is tethered by a wire so that it flies in a circle How could you calculate the tangential speed of the airplane if the line breaks?

If you simply measure the circumference of its orbit (length of string multiplied by 6.282) and then the time it takes to complete a lap, you will find out its speed. This should be the same as the tangential speed if the tether breaks.

# A car is travelling at a given instant 40m per ecs on a circular road of radius 400m.its speed is increasing at the rate of 3m per sec.what is its tangential acceleration?

if the speed is increasing at 3 m/s 2 then that is the acceleration (if i understand the question correctly)

# What is the tangential speed of a passenger on a Ferris wheel that has a radius of 15 m and rotates once in 40 s?

The tangential speed of a point on the outer rim of the wheel is (circumference) divided by (time per rotation) = (30 pi) / (40) = 2.356 meters per second. (rounded) The passenger's tangential speed depends on how close to the rim he sits. Anywhere on the wheel, it has to be 2.356 meters per… second or less. ( Full Answer )

# Is angular velocity the same as tangential velocity?

No. If you can drive around a ten-mile track in the same time it takes you to drive around a one-mile track, then your angular velocity is the same in both cases. But in order to do that, you'll need much higher tangential velocity during the longer run. Tangential velocity is what you'd norm…ally call your 'speed' as you blaze around the track. ( Full Answer )

# What state in the US has the least tangential speed as Earth rotates around its axis?

Alaska, because the distance around the earth at its latitude is smaller than the distance around at the latitude of any other state, so it covers the least distance in one day.

# What is the difference between tangential and shear stresses?

A shear stress results from in plane shear loads; a tangential stress applies to a circular shape, such as a hoop, and is a tensile or compressive stress, not shear stress

# Is the tangential velocity of a rotating object greater when it is close to the center of rotation or when it is far from the center of rotation?

The tangential velocity is greater as the radius of the point on the rotating object increases. For a rotating object v = rw Where v is the tangential velocity r is the radius of the point And "w" is omega or angular velocity (in radians per second)

# How tangential acceleration produced in a body?

Tangential acceleration is d/dr mcV = mc dVcdt = mdv/dt. The tangential acceleration is dV/dt is produced from the Vector Energy (mcV, the "Dark Energy"). Newton "added" the tangential acceleration as " dV/dt" to balance he Gradient acceleration v 2 /r 1R.

# What is the difference between tangential acceleration angular acceleration and centripetal acceleration?

Tangential acceleration is acceleration in the direction of travel, i.e. tangent to the instantaneous velocity. Centripetal acceleration is perpendicular or normal to that, specifically, in the direction of the acceleration, i.e. towards the center of the circle of travel. Angular acceleration is an…ything in between, or outside of those two definition, i.e. not tangent and not normal. ( Full Answer )

# Is it grammatically correct to say tangentially related?

Sure: it is an adverb modifying an adjective. The sentence "It smells purple" is grammatically correct, too. Depending on context, somewhat related or distantly related is probably better.

# What happens to tangential speed as rotational speed increases?

we can say that tangential speed of the object is linearly proportional to the distance from the center. Increase in the distance results in the increase in the amount of speed. As we move to the center speed decreases, and at the center speed becomes zero.

# Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?

No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal accele…ration is zero. However, this would only exist for that small instant in time. ( Full Answer )

# 1.What is the name of a shape with two semi-circles connected by two straight lines that are tangential with the semi-circles 2.Is there a different name if the semi-circles are of different diameter?

Answer to part 1 = Oblong (ellipsoidal rectangle) Answer to part 2 - possibly egg-shaped? Probably still oblong though.

# Why do cars running very fast in a curve road tend to move out of the road in a path tangential to the curve road?

This is because of the car's momentum. Momentum is the tendency of an object in motion to remain in motion upon a straight line trajectory unless acted upon by an outside force. Even though the car may be moving at a constant speed, its velocity is changing because it is turning and therefore changi…ng its vector. This actually happens at any velocity, but it is most noticeable at higher speeds and in heavier vehicles because the magnitude of the momentum being overcome is greater. ( Full Answer )

# What is the tangential speed of an object moving in a circle with a radius of 5 that is going around 3 times in 4 seconds?

I suggest you calculate the total distance travelled (use the formula for the circumference of a circle), then divide this result by the time to get the speed.

# Why is velocity tangential to the path of a body?

Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.

# What is the difference between radial acceleration and tangential acceleration?

The difference is in the direction of the acceleration. Tangential acceleration is in the direction of movement. Radial acceleration is at right angles to it (towards, or away from, the center of a circle for example).

# Why tangential acceleration is not produced in uniform circular motion?

Because there is no tangential force acting on the object in uniform circular motion. The proof that there is no tangential component of acceleration is the fact that the tangential component of velocity is constant.

# What kind of velocity is provided by the news channel in reference to a tornado Is it tangential velocity or angular velocity?

In terms of wind velocity, it would be tangential velocity, as thatis what tells the speed at which the wind is actually moving.Though in truth it is somewhat more complicated than this, as atornado does not behave as a simple rotating object. In terms of atornado's traveling velocity, it is linear …velocity, as a tornadowill generally move along a mostly straight path. ( Full Answer )

# What does it mean when moving in a curve has a tangential velocity?

Picture one of the following: .
a hockey player about to hit a puck with their stick .
a cricket batsman about to strike the ball .
a baseball player about to hit the ball with their bat .
a tennis player about the hit the ball with their racket .
a golfer about to hit the ball with their club… In each of these three cases the motion of the object the player isusing to strike the ball or puck is curved; it's approximatelycircular. However, the motion imparted to the ball or puck isdefinitely not curved. It's essentially straight. It will have thedirection that the club or stick or racket had at the instant thatit struck the ball or puck, and it will have the some of the speedthat the club or stick or racket had at that instant. The total speed and the direction that a club or stick or racket orbat could have imparted to something at a point would be itstangential velocity. Obviously hitting something slows the strikingobject down. ( Full Answer )

# What is the tangential speed of the sun?

Speed, compared to what? The Sun's apparent speed in the sky, from our point of view, is approximately 15 degrees an hour. The Sun's speed around the center of the Milky Way is approximately 220 km/second. I believe that most of that is tangential speed.

# What is an example of tangential and centripetal acceleration?

If an object follows a circular path, it must have a centripetal force on it to keep it moving in a circle. Centripetal means "toward the center of the circle". The force causes Centripetal acceleration toward the center witch is along the radius of the circular path. Tangential acceleration occu…rs at a Tangent to the circular path and is always perpendicular to the centripetal acceleration. Always perpendicular to the radius of the circle. ( Full Answer )
