Question

What will be the kinetic energy if the velocity of an object is doubled?

Answer 1

Answer:

Because kinetic energy is proportional to the square of the velocity, when velocity is doubled, kinetic energy is quadrupled.

Hope it will help you.

Answer 2

Answer:

If velocity is doubled, Kinetic Energy increases by 4 times. Kinetic energy of a body is the energy possessed by it, by virtue of its motion, i.e. if the body is moving it will always have kinetic energy.
