Kinetic energy at velocity "V" is (0.5) x mass x V x V
Kinetic energy at velocity "2V" is (0.5) x mass x 2V x 2V
Ratio of KE at velocity 2V and KE at velocity V is
[(0.5) x mass x 2V x 2V] / [(0.5) x mass x V x V] = 4
So if the velocity double, KE quadruples

How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
As an object falls the gravitational potential energy of the object is converted to what?
Some of its potential energy changes to kinetic energy.
How the kinetic energy of an object changes when the speed of the object doubles?
Look at the formula for the kinetic energy of an object: KE = 1/2 M V2Did you notice that " V2 " ? That means the KE is proportional to the squareof the object's velocity.So if the object's speed doubles, its KE increases by (2)2 = a factor of 4.
What happens to an object's kinetic energy when its speed doubles?
-It increases
What makes an object have more kinetic energy?
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
If the of an object doubles Its kinetic energy doubles?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.

What has potntial energy that changes to kinetic?
A falling object changes from gravitational potential to kinetic.
If the speed of an object doubles the kinetic energy of the object?
At twice the speed, the kinetic energy will be four times greater.
What happens to an object's kinetic energy when its speed doubles?
-It increases
What type of energy change results when friction slows an object down?
The kinetic energy of the object changes into thermal energy.
What An Object falls towards the ground what Happens to the potential energy of the Object?
As an object falls from a higher level to a lower level, the gravitational potential energy that it had at the higher level changes to kinetic energy. As more and more potential energy changes to more and more kinetic energy, the increase of kinetic energy shows up in the form of greater speed.
What makes an object have more kinetic energy?
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
Explain how the kinetic energy of an object changes when the speed of the object doubles?
Kinetic energy is (1/2) (mass) (speed)2 .The only part of that formula we need in order to answer the question isthe (speed)2 part. It says that if you multiply the speed by 'K', then thekinetic energy gets multiplied by K2 .So if you double the speed, the kinetic energy is multiplied by (2)2 = 4 .
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.
