1. The Law of Conservation of Energy states that the total energy of an isolated system remains  .

2. Energy can be transformed from one form to another, such as potential energy converting into   energy.

3. A system that does not exchange matter or energy with its surroundings is called an   system.

1. Describe the energy transformations that occur when a ball is thrown vertically upwards and then falls back down.

2. Explain why the Law of Conservation of Energy is a fundamental principle in physics.
