Question

Define kinetic energy of an object? What will happen to the kinetic energy of a body if its velocity is doubled?​

Answer 1

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.

Answer 2

ANS:- Kinetic energy is the energy that an object possesses due to its motion. It is basically the energy of mass in motion. Kinetic energy can never be negative and it is a scalar quantity i.e. it provides only the magnitude and not the direction.

ANS:- If velocity v is doubled, the kinetic energy becomes four times as kinetic energy is directly proportional to the square of velocity.
