Is the light produced by fluorescent lights potential kinetic or radiant energy?
The light produced by fluorescent lights is radiant energy. It is in the form of electromagnetic radiation that is visible to the human eye.
How do you convert 3 meter per second into seconds?
0.83333. A meter per second is a unit of speed. One meter per second is exactly 3.6 kilometers per hour, or about 2.237 miles per hour.
How many miles per hour is 300 kilometers per hour?
1 mile = 1,234,567,890,012,345,678,901,234,567,890,123,455,678,900 mm
1 hour = 3,600 seconds
3000 inches / 63,360 in/mile = 0.0473484848 miles/sec * 3,600 sec/hr =
170.45 mph
An energy resources are ways of getting energy. For example we get energy (electricity) from the wind. We get energy from the wind by using wind turbines. You can also get energy from biomass and coal. Hope this helps!
What are the examples of kinematics?
if we assume an example of crank slotted lever mechanism then if we consider only the part where we are not considering the cause of motion but the effect of motion. like we are looking for the motion we are just making rotary motion to linear motion, if we are interested we can find out the velocity and acceleration factor ram over linearly moving part.
so in one word we can say that kinematics is not a consideration with cause of motion but the effect of motion.
No, 1 m/s^2 means that an object's velocity is increasing by 1 meter per second every second. So, in the first second, the velocity of the object will be 1 m/s, in the second second, it will be 2 m/s, and so on. The acceleration is constant and the velocity increases linearly with time.
What is the limited top speed of a 2004 dodge ram?
The limited top speed of a 2004 dodge ram 5.7L hemi is 170km/h
* A scalar is just a number, used to represent the magnitude of something. thus, 35 is a scalar number that can mean that something is 35 inches long, 35 meters high, 35 years old, or etc. * A vector is a magnitude that has a direction. usually this is represented by magnitudes on axes that are perpendicular to each other. so, the vector ( 5 7 ) (usually written with the 5 over the 7, but the software here won't handle that) means the line from (0,0) to (5,7). notice that this line has both a magnitude (length) and a direction: i.e., it points in a different direction than the vector ( 7 5 ) but has the same magnitude, and points in the same direction as the vector ( 10 14 ) but has a different magnitude. * A tensor is a vector that has a position in space. vectors (by definition) all begin at the origin (0,0); tensors are constructed the same way but can have their origin anywhere.
What is the formula for force?
One formula for force is Newton's Second Law of Motion: Force = Mass * Acceleration or F = ma
On the earth's surface, F=mg
where
F= weight
m= mass
g= acceleration due to gravity
In fact, force is the rate of change of momentum and is given by:
F = dp/dt
where p is momentum.
F = dp/dt can be expanded to F = v(dm/dt) + m(dv/dt)
where m is mass, v is velocity.
F = m(dv/dt) = ma. This is for constant mass.
F = v(dm/dt) is used when velocity is constant but mass is changing.
If an object covers equal distance in equal intervals of time, we can say that the object is moving with a uniform speed. E.g. consider an object moving along straight line. Let it travel 5 m in the first second, 5 m more in the next second, 5 m in the third second and 5 m in the fourth second. In this case, the object covers equal distance in equal intervals of time so we can say that the object is moving with a uniform speed.
What causes change in velocity?
If an object's velocity changes -- if its speed increases or decreases or if its direction changes -- that means it has accelerated. For an object to accelerate, the sum of the forces acting upon it must be non-zero. So, in other words, forcechanges an object's velocity.
Is the coefficient of dynamic friction greater than the coefficient of static friction and why?
Millions of classroom experiments would indicate that there is, in fact, a difference, but it is most likely caused by dirt, oil, and imperfections on the surfaces. When care is taken to ensure the surfaces are uniform and clean, the difference between static and dynamic friction disappears.
How do you calculate velocity?
given distance- 200km
time-5 hours
speed- distance/time
200/5
40km/hr
Divide distance by time for speed
Divide speed by distance for time
Multiply speed and time for distance
Those are three ways to make sure you have it right
Average Velocity = (change in position) / (elapsed time)
Instantaneous Velocity = [limit as elapsed time approaches 0] (change in position) / (elapsed time)
Velocity is measured in m/s+ direction
How does speed increase the weight of a moving body?
Speed does not increase the weight of a moving body. Weight is determined by the mass of the object and the force of gravity acting on it, and it remains constant regardless of speed. Speed only affects the kinetic energy of the body, which is proportional to the square of the speed.
If you are Traveling at 1 mile per second how many minutes does it take to travel 1000 miles?
It would take approximately 16.67 minutes to travel 1000 miles if you are traveling at 1 mile per second. This calculation is based on dividing 1000 miles by 60 seconds (which equals 16.67 minutes).
A body is said to move with uniform velocity if it has no acceleration. This implies that the body moves with a constant speed along a straight line path.
This also means that the body moves with equal displacements in equal intervals of time, however small these time intervals may be.
What is potential energy and kinetic energy?
In a system the potential energy is related to forces acting between bodies inside the system. Kinetic energy of a moving body is defined as K=(1/2)*m*v^2 where m is the mass of the body and v its velocity. If no energy is transfered to or from the system then the sum of the system's kinetic and potential energy remains constant.
answer2: The universe is composed or quaternions, a real number or scalar and 3 vector numbers. Energy has these two types the potential energy is the real part and kinetic energy is the vector part, for example take gravity energy:
E = Pot + Kin = -mGm/r + mcV = -mu/r + mcV ,
where the potential gravitational energy is the scalar part and mcV is the kinetic vector energy. V is the velocity vector.
Currently Physics defines "energy as a scalar" in spite of Torque, a vector FxR with units joule or Newton -meter.
Well, kinetic energy is the energy of motion and potential energy is the energy of position
Potential Energy. Stored energy that results from the position or shape of an object.
Kinetic Energy Energy that an object has due to its motion.
History
A roller coaster train going downhill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster rider is in an gravitational field except with the Principle of Equivalence.
Potential Energy
Potential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill. The higher the train is lifted by the motor the more potential energy is produced; thus, forming a greater amount if kinetic energy when the train is dropped. At the top of the hills the train has a huge amount of potential energy, but it has very little kinetic energy.
Kinetic Energy
The word "kinetic" is derived from the Greek word meaning to move, and the word "energy" is the ability to move. Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be. As the train accelerates down the hill the potential energy is converted into kinetic energy. There is very little potential energy at the bottom of the hill, but there is a great amount of kinetic energy.
Theory
When the train is at the top and bottom of the hill there is not any potential or kinetic energy being used at all. The train at the bottom of the first drop should have enough energy to get back up the height of the lift hill. The "Act of Faith" in riding these amazing rides which seems more of a phenomena that is only a theory. In practices, the train never could make it back up the hill because of dissipative forces. Friction and air resistance, and even possible mid-course breaks, are dissipative forces causing the theory to be changed but not destroyed. These forces make it impossible for the train to have enough energy to make it back up the lift hill's height. In the absence of the dissipative forces the potential and kinetic energies(mechanical energy) will remain the same. Since the mechanical energy is destroyed by the forces, the first hill is always the highest.
KINETIC POTENTIAL ENERGY,
iS the ammount of energy one has, then the other is stopped and it goes down a hill or something steep.
What causes Ticking on acceleration?
If it sounds like rocks in a can, or like a Diesel engine, you might be experiencing detonation, which is really bad. It is caused by poor gas and/or ignition timing too advanced. Left unfixed, it will melt holes in your pistons.
To fix, get higher-octane fuel and/or retard timing
V = Vo + at
X - Xo = Vot + .5at2
v2 = vo2 + 2a(X - Xo)
X - Xo = .5(Vo + V)t
V is final velocity in units of meters per seconds (m/s)
Vo is initial velocity in units of meters per seconds (m/s)
a is acceleration in units of meters per squared seconds (m/s2)
t is time in seconds (s)
X is final displacement in units of meters (m)
Xo is initial displacement in units of meters (m)
Multiple unknowns can be solved for each other by using more than one equation. If you are solving for two components, find a common piece (such as time), solve for that piece for each component and set them equal to each other to solve for the other unknowns.
Hope this helps!
p.s. sometimes it is easier to remember the second, third and fourth equations as
2. df - dI = vIt + .5at2
3. v2=vI2+2a(df - di)
4. df - dI = .5(vI + vf)t
its all the same except x has been switched with the first letter of displacement, and the 0 have been switched with i for initial. f is for final
What is the advantages of friction?
Friction provides grip and traction between surfaces, enabling us to walk, drive, and perform various tasks. It also allows us to control the speed of objects and prevent slipping or sliding. Additionally, friction helps in converting kinetic energy into heat, which can be useful in machines and brakes.
What is the coefficient of friction in a 6 inch round duct with a velocity of 200cfm?
The coefficient of friction for air flow in a round duct is typically around 0.02. This coefficient may vary depending on factors such as surface roughness and airflow conditions.
Holly trees typically grow at a slow to moderate rate, averaging about 12-24 inches of growth per year depending on the variety and growing conditions. It can take several years for a holly tree to reach its full mature height.
The increase of velocity over a period of time is?
Acceleration is the rate of change of velocity over time. So, if velocity is increasing over a period of time, there is acceleration present.

What two factors determine the potential energy of an elevated object?
Potential energy can be descirbed in many forms: gravitational potential, electrical potential and so forth.
For gravitational potential energy, the formula is E=mgh, where E is the gravitational potential energy, m is the mass of the object , g is the strength of the prevailent gravitational field and h is the height above that field. In this instance, the factors determing the potential energy are threefold; the mass, the gravitational field strength and the height.
For electrical potential, the factors vary depending on what electrical field, componant or senario you are dealing with. In essence, an object has electrical potential energy when it has become charged (such as an Ion), or it is feeling the effects of conflicting magnetic feilds and motion (as in electro-magnetic induction).
