Gravitational potential energy is a form of energy that depends on changes in the height of an object. The higher an object is, it will have more gravitational potential energy. If a body with mass m is elevated a distance h, the change in gravitational potential energy of that object is:
[tex]\Delta U=mgh[/tex]Where g is the gravitational acceleration:
[tex]g=9.81\frac{m}{s^2}[/tex]Kinetic energy is a form of energy that depends on the speed of an object. The faster an object moves, more kinetic energy it will have. If an object with mass m moves at speed v, its kinetic energy K is given by the expression:
[tex]K=\frac{1}{2}mv^2[/tex]
