State the equation for gravitational potential energy? 
Gravitational potential energy = mass x height x gravitational field strength
State the equation for electrically transferring energy?
E=Pt
State the law of conservation of energy?
energy cant be created or destroyed it only be transferred
Define chemical energy?
energy stored in foods,fuel,batteries
Define thermal energy?
Energy stored in objects depending on their temperature (higher temperature=more thermal energy stored)
What are the three types of fossil fuel?
