Part 1:** All students complete these**

Directions:

Several energy sources are listed below. Decide whether each is a representative of PE or KE by writing the correct word in the energy source column. If an energy source is potential, explain what happens when it is converted to kinetic energy. The first question has been done for you as an example.

Part 2: **Calculations: High School only completes these**

1. You serve a volleyball with a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. The ball has ____________ energy. Calculate it.

2. A baby carriage is sitting at the top of a hill that is 21 m high. The carriage with the baby weighs 12 N. The carriage has ____________ energy. Calculate it.

3. A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. The car has ___________energy. Calculate it.

4. A cinder block is sitting on a platform 20 m high. It weighs 79 N. The block has _____________ energy. Calculate it.

5. There is a bell at the top of a tower that is 45 m high. The bell weighs 190 N. The bell has ____________ energy. Calculate it.
