WebPotential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. However, it isn’t affected by the environment outside of the object or system, such as air or height. On the other hand, kinetic energy is the energy of an object or a system’s particles in motion. WebKinetic Energy: The kinetic energy of a moving object: k = 1 2 mv 2 • Kinetic energy is proportional to the square of the velocity. If the velocity of an object doubles, the kinetic energy increases by a factor of four. • Kinetic energy is proportional to the mass.
