P1-Energy

Energy stores and systems 

A system is an object or group of objects that interact with each other.

Chemical energy is stored in fuels or batteries.

Changes in energy

Gravitational potential energy is energy stored by systems with objects that are high up. The higher it is lifted the higher the GPE. If it falls it looses GPE.

 E_p = m x g x h       GPE = mass x gravity feild strength x height

Kinetic energy is stored by moving objects. If an object isn't moving the kinetic energy is 0. The amount of energy stored depents on the mass…
