What is 1 kph in mph?

1 kph is approximately equal to 0.62 mph.

What is the mathematical model for a velocity vs time graph?

The mathematical model for a velocity vs time graph is v(t) = v0 + at, where v(t) represents the velocity at time t, v0 is the initial velocity, a is the acceleration, and t is the time. This equation describes the relationship between velocity, acceleration, and time.

How is potential energy similar to kinetic energy?

Mass

Kinetic energy = 1/2 · mass ∙velocity2

Potential energy = mass ∙ (acceleration due to gravity) ∙ height

Mass is common to both

Kinetic energy is the energy due to motion. The faster an object (mass) is moving; the more Kinetic energy is has.

Potential energy is the energy due to position. The higher an object (mass) is off the earth's surface, the more Potential energy it has.fcfytrdddrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrtdjgrfxnzsdfcxzdfgv dorkk

What is the importance of a ballistic test?

Ballistic tests are important for evaluating the performance and effectiveness of bulletproof materials, such as body armor and vehicle armor. By subjecting these materials to controlled ballistic impacts, researchers and manufacturers can assess their ability to withstand bullets and projectiles, ensuring that they provide sufficient protection to users. Additionally, ballistic tests help in the development and improvement of armor technology to keep pace with advances in weaponry.

Find the speed in feet per second of a baseball pitched at 87 mph?

To convert 87 mph to feet per second, you can use the conversion factor of 1 mph being roughly equal to 1.47 feet per second. Therefore, a baseball pitched at 87 mph would be traveling around 128 feet per second.

What happens to an object as its kinetic energy increase?

As the kinetic energy of an object increases, its speed and momentum also increase. This means the object will have more energy to overcome resistance or obstacles in its path. Additionally, if the object collides with another object, the impact will be more forceful due to the higher kinetic energy.

What are the units of the coefficient of friction?

The coefficient of friction is a unitless value because it represents a ratio of the force required to move an object over a surface to the weight of the object. Since it is a ratio of two forces, it does not have any units associated with it.

What is the top speed of a koeningsegg ccxr?

The top speed of a Koenigsegg CCXR is approximately 250 mph (400 km/h).

Sum of the total kinetic and potential energy of a substance?

The sum of the total kinetic and potential energy of a substance is known as its total mechanical energy. In a closed system, this energy remains constant, as energy cannot be created or destroyed, only transferred between kinetic and potential forms. The total mechanical energy is the sum of the kinetic energy (energy due to motion) and potential energy (energy due to position or state) of the substance.

When kinetic energy doubled what happens to momentum?

If kinetic energy is doubled, the momentum will remain the same. Kinetic energy and momentum are related, but momentum depends on mass and velocity while kinetic energy depends on mass and velocity squared. Therefore, doubling kinetic energy will not affect momentum.

Kinetic friction is best described as the frictional force that acts to?

oppose the motion of an object in contact with a surface. It is dependent on the nature of the surfaces in contact and the normal force pressing them together.

Can an object have a varying speed it its velocity is constant?

Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.
Yes. Velocity is (speed and direction of motion). If direction changes, then velocity

changes, even if speed is constant.

Examples:

-- Car going around a curve at a constant speed has changing velocity.

-- Anything traveling a circular path at a constant speed has changing velocity.

When do two different distance-time graphs have matching velocity-time graphs?

Two different distance-time graphs have matching velocity-time graphs when the slope of the distance-time graph represents the velocity in the velocity-time graph, as velocity is the derivative of distance with respect to time. This means that the steeper the distance-time graph, the greater the velocity on the velocity-time graph at that point.

How would one determine Acceleration from a V-t Graph?

Acceleration can be determined from a velocity-time graph by calculating the slope of the line on the graph. The steeper the slope, the greater the acceleration. If the graph is curved, acceleration can be calculated by finding the tangent to the curve at a specific point.

True of false The acceleration of an object is inversely proportional to the net force acting on it?

False. The acceleration of an object is directly proportional to the net force acting on it.

Newton's 2nd Law:

F = ma

where F is the force, m is the mass, and a is the acceleration.

__________________________________________________

The acceleration of a body is "inversely" proportional to its mass.

Does the inside of a plane have Kinetic Energy?

Each mass object in there has.

That's why it's harder to take off when the plane is full ... the engines have to pump all that kinetic energy
into every suitcase and body inside.

Can an objects acceleration increase if you drop it from a higher altitude?

Yes, an object's acceleration remains constant regardless of the height from which it is dropped. However, the object will achieve a higher velocity when it lands after being dropped from a higher altitude due to its longer time in free fall.

What lab equipment is used to measure time?

Usually a stopwatch. Higher quality stopwatches will give better resolution in results.

How many mph can a bus go?

Well, first of all what kind of bus. It depends on the type and manufacturer as well as model of the bus. A school bus will barley do 65 mph in general, while a city bus might do 75-80 mph. A grey hound type bus will easily do 80 mph.

What is the top speed of a CRF230?

A CRF 230 will top out at between 65 and 75 mph.

How would you compute the resultant velocity given a linear velocity and an angular velocity?

by using trig. So draw a triangle out with the given information. for example 1 line is 12m/s, another line is Um/s (u for unknown) and one line is resultant velocity. add your angle in and use trig to work out what you want.

Is acceleration the slope of velocity vs time graph?

No, acceleration is the rate of change of velocity with respect to time. It is the derivative of the velocity function, not the slope of the velocity vs. time graph. The slope of the velocity vs. time graph represents the rate of change of velocity, not acceleration.

How fast is 200kmph im mph?

200 kph = about 124.3 mph
200 kilometers per hour is 124.27 miles per hour.

How many mph does a bugatti go?

400MPH

LOL it could dp only 263 mph but it's limited to only 258 because if it went beond 263 the tyres would burst and/or the car would of take off do the the g-gorces and central gravity
