1. Energy Basics

2. Relationships Between Matter and Energy
Matter is anything that occupies space and has mass.
Energy is the capacity to take action and move matter around.
How are energy and matter related?
Energy is stored in matter.
Energy moves matter.
Conservation of Matter
The total mass of Earth is constant, because Earth is neither gaining or losing mass.
Matter cannot be created or destroyed, but it can be rearranged.
Conservation of Energy (First Law of Thermodynamics)
Energy cannot be created or destroyed, but it can be transformed from one form into another.

3. Forms of Energy Mechanical Energy Potential Energy Kinetic Energy
The total energy an object has due to its position, movement or both
Mechanical Energy
Energy that is stored and ready to be used, due to an object’s position or condition.
Potential Energy
Energy that is released due to an object’s movement or motion
Kinetic Energy

9. 2nd Law of Thermodynamics – ‘The Agony of Heat’
No energy is actually lost, but ‘useful’ energy is lost.
