Question

if tif the velocity of a body is double its kinetic energy​

Answer 1

Answer:

Hey Mate your answer is here

Explanation:

Momentum is directly proportional to velocity. If momentum of an object is doubled, but its mass does not increase (so velocity remains below the speed of light) then its velocity is doubled. If the velocity is doubled, then the kinetic energy increases by four times.

Answer 2

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.
