Match each term to its meaning
Draw a line connecting each term on the left to its correct description on the right, or write the matching letter next to each term.
| Term | Your answer | Description |
|---|---|---|
| Work | A. The energy a moving object has | |
| Kinetic energy | B. Stored energy in a stretched band, a squashed spring or a lifted object | |
| Potential energy | C. What happens when a force makes something move and transfers energy | |
| Friction | D. The rule that energy is never created or destroyed, only moved or changed | |
| Conservation of energy | E. A force between rubbing surfaces that turns movement energy into heat |
Fill the gap
Choose the correct word from the word bank to complete each sentence. Two words will not be used.
When a force makes an object move, we say the force does . A moving object has movement energy, which is also called energy. A stretched elastic band stores elastic energy until you let go. Lifting a bag up high stores energy because you push it against . When you rub your hands together, friction turns movement energy into . Energy is always , which means it is never created from nothing.
1. A student says: "When I kick a ball and it speeds away, no energy moved anywhere." Is the student correct? Explain your answer.
2. Name one example of a force storing energy and one example of friction turning movement energy into heat.
