If all else is constant, which would cause the greatest increase in kinetic energy of a moving object? mass and velocity are each reduced by one-half. mass is reduced by one-half, and velocity is doubled. mass is doubled, and velocity is reduced by one-half. mass and velocity are each doubled.

(D) Mass and velocity are each doubled.
