What is the law of mechanical energy?

22.5 Conservation of mechanical energy (ESAHO). Conservation of Energy. The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. So far we have looked at two types of energy: gravitational potential energy and kinetic energy. read more

In physics, if you know the kinetic and potential energies that act on an object, then you can calculate the mechanical energy of the object. Imagine a roller coaster car traveling along a straight stretch of track. The car has mechanical energy because of its motion: kinetic energy. read more

The Law of Conservation of Energy takes into consideration ALL types of energy, not just mechanical energy. 2. The Law of Conservation of Energy is always fulfilled. read more
