JC Physics A. Roche 2010

What is Energy? Energy is the ability to do work or move something. Energy is measured in Joules (J).

1.Kinetic – Moving 2.Chemical – Fuel, Food & Batteries 3.Electrical 4.Potential – Gravitational or stored in shape 5.Light 6.Heat 7.Sound 8.Nuclear 9.Magnetic Energy can exist in many forms. What are the different forms of energy?

What is The Law of Conservation of Energy? The Law of Conservation of Energy states that: Energy cannot be created or destroyed but can be converted from one form to another.

Energy Conversions Kinetic Chemical Electrical Potential Light Heat Sound Nuclear Magnetic Kinetic Chemical Electrical Potential Light Heat Sound Nuclear Magnetic

Experiment To convert Light energy to Electrical energy to Kinetic energy

Experiment To convert Chemical energy to Electrical energy to Heat energy

Experiment To convert Electrical energy to Magnetic energy to Kinetic energy

Renewable and Non-renewable Energy Sources? Renewable Energy Sources wont run out. Non-renewable Energy Sources will eventually run out.
