- Energy cannot be created or destroyed by ordinary physical or chemical processes.
- This concept is called the law of conservation of energy.
- Throughout the experiment, the total amount of energy must remain constant.
- When potential energy goes down, kinetic energy increases.
- When potential energy goes up, kinetic energy decreases.
