Answer: mass and velocity (speed)
Explanation:
Kinetic energy is the energy possessed by a body due to its motion, e.g a moving car. It is measured in joules.
Thus, Kinetic energy = 1/2 x (Mass x velocity^2)
For instance:
A moving car that has a mass of 10 kg and runs with a velocity of 2m/s will have a kinetic energy of 20 joules.
Thus, the mass and velocity (speed) of an object impact kinetic energy.
