Document: Kinetic Energy Facts: - An object keeps the same amount of kinetic energy unless it speeds up or slows down. |
| - Kinetic energy can be calculated for any moving object as long as the objects' mass and speed are known. |
| - The unit used when measuring kinetic energy is called a joule. |
| - Kinetic energy can occur in any direction whether up and down or left to right. |
| - When an objects' mass doubles, its kinetic energy also doubles. |
| - When an objects' speed doubles, its kinetic energy quadruples. |
| - The faster an object moves, the more kinetic energy it has. |
| - When an object collides with another object, it transfers its kinetic energy to the other object. |
Task 1 : Use your brain, the document and the videos to answer the questions below:
- What does Potential Energy depends on ? Propose a formula
- What does Kinetic Energy depends on ? Propose a formula
Call the teacher to check your answer. Then exercice on Potential Energy and Kinetic Energy.
