Mechanical

Mechanical energy is the sum of the kinetic energy and the potential energy of objects in a system. This includes elastic potential energy and gravitational potential energy. Some examples of mechanical energy are:

• swings,
• bicycles,
• automobiles, and
• roller coasters.

The mechanical energy of a system generally remains constant. When the energy remains constant, it is only transformed between different types of mechanical energy (kinetic, gravitational potential, and elastic potential).
