MECHANICAL ENERGY

By: Julie Jevahirian. Jacob Anderson, Tess Helfrich, and Josh Gates

DEFINITION

Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).

Objects have mechanical energy if they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position).
