If the velocity of the body is increased twice then how many times K.E is increased

Answer: 4
Explanation

The kinetic energy is mathematically expressed as K. E=12mv2,

where m is the mass of the body and v is the velocity with which the body is moving

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