It doubles.
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
momentum is doubled, kinetic energy is quadrupled
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.

If the velocity is doubled, then the kinetic energy increases by 4 times
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
Twice the mass --> twice the kinetic energy.
momentum is doubled, kinetic energy is quadrupled
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.

If the velocity is doubled, then the kinetic energy increases by 4 times
since kinetic energy is proportional to the square of velocity it is multiplied by 2 x 2 which is 4
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.
The kinetic energy would be quadrupled, and the momentum would be doubled.
If the velocity of Earth were to double, it would have 4 times the kinetic energy. Twice the current kinetic energy would already be enough to catapult the Earth away from the Sun - never to return.
Kinetic energy will also be halved. Because kinetic energy is equal to 1/2 mv2
