Q. If the momentum of a body is doubled, the kinetic energy__:
Answer: becomes 4 times
Notes: The momentum of a particle is given by the equation, P = mv, where P is the momentum of the particle, m is the mass of the particle, and v is the velocity of the particle. The kinetic energy of a particle is given by the equation, KE = . mv2. So, if momentum is doubled, kinetic energy increases four times.
