Question

The kinetic energy of an object of
mass, m moving with a velocity
of 5 ms-l is 25 J. What will be its
kinetic energy when its velocity
is doubled? What will be its
kinetic energy when its velocity
is increased three times?
​

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

Anwer:

Since Kinetic energy id directly proportional to square of velocity
