Kinetic Energy is energy that a body possesses by virtue of being in motion.
Potential Energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
How do we use Kinetic Energy and Potential Energy in everyday life? - We use kinetic energy and potential energy in baseball.Like when the pitcher winds up and gets a balancing point that is Potential Energy. Then when he steps and releases the ball he is using Kinetic energy . He demonstrates both potential energy in the windup, and kinetic energy in the pitch.
