| Question | Answer |
|---|---|
| What is potential energy? | The energy stored in an object because of its position. |
| What is kinetic energy? | The energy an object has due to its motion. |
| At what point on a roller coaster can you measure the highest potential energy? | The potential energy is transformed into kinetic energy. |
| A ball rolls down a hill and then stops at the top of the next hill. Where is the kinetic energy the greatest? | At the top of the largest hill because it has the most potential to cause change. |
| Potential energy is in the process of increasing when something is going.... | Potential energy increases as the object is going uphill. |
| Kinetic energy ________ as a ball rolls down a hill. | Increases |
| Potential energy ________ as a ball rolls down a hill. | Decreases |
| What has an effect on potential energy? | Height and mass |
| What has an effect on kinetic energy? | Mass and speed |
| What is the Law of Conservation of Energy? | Energy is neither created nor destroyed. |
| Two forms of energy | Potential and kinetic |
| Kinetic energy ______ as potential energy decreases. | Increases |
| Kinetic energy ______ as potential energy increases. | Decreases |
| What causes a pendulum to stop moving? | Air resistance creates friction that slows the pendulum down until it stops. This causes the gravitational energy to become potential energy. No energy is destroyed. (This is the Law of Conservation of Energy) |
| Energy due to is ______ energy. | Kinetic |
| _________ is the ability to cause change. | Energy |
| The faster an object moves, the ____ kinetic energy it has. | More |
| ______ energy is stored energy. | Potential |
| What kind of energy is a stretched rubber band? | Potential |
