If the velocity of an object doubles, how the momentum and the kinetic energy of the object change? * O momentum does not change because it is always conserved, and the kinetic energy doubles. Momentum doubles, but the kinetic energy does not change because the kinetic energy is a scalar quantity momentum doubles and the kinetic energy increases to four times higher Both of them do not change because they are depend on the speed of the object rather than the velocity.
