The numerous forms of energy can be classified into two different categories: kinetic energy and potential energy.
Kinetic Energy
Kinetic energy is the energy of an object in motion.
All matter is made up of tiny particles. These particles are moving all the time, so they have kinetic energy.
Thermal energy is the total amount of all the kinetic energy of every particle in an object or substance. When this kinetic energy transfers to another object or substance, it is called heat.
When friction does work on an object, some of the energy of the object is transformed into thermal energy. An increase in thermal energy causes an object to be warmer.
As energy is being transferred, some amount of thermal energy is always produced.
Potential energy is energy that is stored, which waits to be used to do work.
Energy does not always involve motion. An object can store its energy to do work later. So any energy that is stored is called potential energy.
Gravitational potential energy is the potential energy of an object that is able to fall. By increasing the height of an object, its potential energy will increase.
