Energy

3. The ability to do work or cause change
5. The amount of matter in an object which affects its potential energy
11. A common example used to show changes between potential and kinetic energy
12. When energy moves from one object or place to another
14. Stored energy that can be released to do work
15. The total energy of motion and position in an object
16. When energy changes from one form to another
19. Potential energy stored when an object is stretched or compressed
20. The unit used to measure energy

1. Potential energy stored in food fuels and batteries
2. Done when a force causes an object to move
4. The energy an object has because it is moving
6. Increasing the length of an elastic object stores potential energy
7. A force that pulls objects toward the centre of the Earth
8. Another word for movement
9. Increasing this increases gravitational potential energy
10. A word that describes potential energy
13. When an object drops its potential energy decreases and kinetic energy increases
17. How fast something is moving which affects its kinetic energy
18. A word that describes kinetic energy
