What happens to an object's kinetic energy when its speed doubles?

-It increases


What happens to speed if kinetic energy halved?

Kinetic energy is determined by mass and velocity. The velocity is halved if you double the original mass, so the kinetic energy stays the same (unless the mass added has the same kinetic energy in the observer's reference frame as the original mass).


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 the kinetic energy of a snowball as it rolls across the lawn and gains mass?

That depends on what happens to its speed. The formula for kinetic energy is:KE = m(v)^2, in which m is mass in kg and vis speed in m/s.If either the mass or the speed increases, the kinetic energy will increase. So if the mass of the rolling snowball increases, but the speed remains constant, its kinetic energy will increase.However, in reality, due to friction between the snowball and the ground, the speed will decrease until the snowball stops. So the kinetic energy under natural conditions would decrease, even though the mass increases.

Example of conversion of gravitational potential energy into kinetic energy?

The simplest example is a falling object. Its potential energy is reduced, while its speed, and thus its kinetic energy, increases.


What will happened to the ke if its velocity is reduced by 12 times?

Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed.

What happens to kinetic energy when the mass and speed of an object changes?

Any change in mass or speed will cause a change in kinetic energy.


What happens to the potential energy as the kinetic of an object increase?

An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
