The kinetic energy of a body is (1/2)mv2, where m is mass and v is velocity. If the velocity were 1/3, then the kinetic energy would be (1/2)m(v/3)2, which is equal to ((1/2)mv2)/9, so when the velocity is decreased by a factor of 1/3, its kinetic energy is decreased by a factor of 1/9.

A particle's kinetic energy is [1/2] times [particle's mass] times [particle's speed]2.

Since the KE is proportional to the speed squared, if the speed increases by a factor of 3,
the KE increases by a factor of (3)2 = 9.

Does kinetic energy increase with speed and time?

Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.


What happens to an objects kinetic energy as its mass increases?

kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.


Do changes in velocity and mass have the same effect on kinetic energy?

Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.


Is kinetic energy a form of energy in the earth's system?

No, not at all. Kinetic energy is energy related to movement - any moving object has kinetic energy; at low (non-relativistic) speeds, the kinetic energy is calculated as 0.5 x mass x velocity squared.No, not at all.

How do you find kinetic energy if no final velocity is given?

Kinetic energy is equal to potential energy during the change

What happens when kinetic energy is absorbed as an object moves toward the earth?

The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.


What happens to an objects kinetic energy as its velocity increases?

Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2


The kinetic energy of the object moving with a velocity of 5 meter per second is 25 joules. What will be the kinetic energy when the velocity is tripled?

The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.


When the speed of body is doubled kinetic energy becomes?

If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.

What happens when you decrease the velocity of a car?

as you decrease the velocity of a car, you decrease the kinetic energy.


What happens to kinetic energy of an object if the velocity is doubled?

If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.


What happens to kinetic energy as velocity increases?

particles speed up.


As kinetic energy increases what happens to mass and velocity?

it speeds up


What happens to an object kinetic energy if the object speed increases?

The kinetic energy will increase. Kinetic energy is defined by K=one half mv2 where m is the mass of the object, and v is the velocity of the object. The greater the velocity, the greater the kinetic energy. Since the velocity is squared, increasing it will cause the kinetic energy to grow much faster than if you increased the mass.


What energy happens when you plug in a blender?

electrical energy becomes kinetic energy and sound energy


When you have kinetic energy you must have?

When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
