Question

Write the relation between kinetic energy and momentum of a body.

Answer 1

Sometimes it's desirable to express the kinetic energy of a particle in terms of the momentum. That's easy enough. Since and the kinetic energy  so



Note that if a massive particle and a light particle have the same momentum, the light one will have a lot more kinetic energy. If a light particle and a heavy one have the same velocity, the heavy one has more kinetic energy.

Answer 2

Answer:

There is a relation between kinetic energy and momentum as both the properties are linked with velocity. Momentum gets expressed as a multiplication of velocity and mass, whereas kinetic energy is the product of the square of speed and half of the mass.
