What is the difference between potential energy and kinetic energy?

State two differences between potential energy and kinetic energy.

Distinguish Between

Solution

Potential Energy Kinetic Energy
It is the energy of a body by virtue of its change in shape, size or configuration. It is the energy of a body by virtue of its motion.
It is independent on the speed of the body. It is directly proportional to the square of the speed of the moving body.
