Kinetic and Potential EnergiesKinetic and Potential Energies

The kinetic energy of an object is given by:

$E{_{k}}frac{1}{2}mv^{2}$

The gravitational potential energy of an object in a uniform gravitational field is given by:

$E{_{p}}=mgh$

When an object falls through a gravitational field, GPE is converted to KE. When it reaches the ground, its GPE is 0 and its KE is at a maximum.
