Recaping previous lessons

What is the definition of energy?

1. Energy is everywhere
2. The ability to do work (in joules)
3. The ability to do work (in calories)
4. Electricity going through cables

What are the two main forms of energy?

1. Physical and mental
2. efficient and inefficient
3. chemical and nuclear
4. Kinetic and potential

Energy types
