All energy is either POTENTIAL or KINETIC. Potential energy is stored energy, either by an object’s position (gravity) or in chemical bonds. Kinetic energy.

All forms of energy fall under 2 categories:  Potential  Kinetic.

Energy Exists in Different Forms What is energy? Energy is the ability to cause change. All forms of energy cause change to occur.

Energy is said to be the ability to do work. That means the ability to make something happen. By “happen” it means to make things move or change condition.

Energy Transformations PS9.15

Energy is found in different forms Kinetic energy types Electrical – the movement of electrons(electricity) Light energy – electromagnetic energy that travels in transverse waves. Heat energy – the vibration and movement of the atoms and molecules in a substance

More kinetic energy types Mechanical energy – the movement of objects from one place to another. Sound – the movement in longitudinal waves. Caused by vibrations.

Potential energy types Chemical energy – energy stored in bonds of atoms and molecules. Propane, natural gas, and petroleum are examples. Elastic energy – energy stored in objects. A compressed spring or a stretched rubber band are examples.

More potential energy types Nuclear energy – energy stored in the nucleus of an atom. Energy is given off by either nuclear fusion or nuclear fission. Gravitational energy – energy of position. Hydropower is an example.
