mechanical energy

Movement and position

Mechanical energy is the energy an object has due to its motion or position.

It combines kinetic energy (energy of movement) and potential energy (stored energy from position or configuration).

A swinging pendulum continuously converts between the two forms.

The mechanical energy of the roller coaster is highest at the top of the first hill.

In physics, mechanical energy is distinguished from other forms like thermal, chemical, or electrical energy.
