physics

 Potential Energy (PE)

Stored energy. 

 Kinetic Energy (KE)

Energy of motion.

Friction

 Causes potential and kinetic energy to decrease by converting some energy to thermal energy

Energy Transformation

The process where energy changes from one form to another. 

Gravitational Potential Energy

Energy stored in objects lifted against gravity

Elastic Energy

Energy stored in stretched or compressed objects

Chemical Energy

Energy stored in the bonds between atoms and molecules

Nuclear Energy

Energy stored in the nucleus of atoms, released during nuclear reactions

 Mechanical Energy

Energy of moving objects

Thermal Energy

Energy from the movement of tiny particles. 

Sound Energy

Energy that travels in waves through matter

Radiant Energy

energy that travels in waves and can move through empty space

 Electrical Energy

Energy from the movement of electrons through a conductor

Force

A push or a pull, measured in Newtons

Newton's First Law

 An object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an outside force. 

 Newton's Second Law

 Force equals mass times acceleration

Newton's Third Law

For every action force, there is an equal and opposite reaction force.
