Down
- 1. An object at rest will remain at rest and an object in motion continues in motion with the same speed and direction unless acted on by unbalanced forces
- 2. energy associated with the motion or position of an object
- 3. object being accelerated, the more force needed to accelerate the object
- 4. energy of motion

- 8. a force that opposes the motion of one object moving past another
- 10. energy contained within a system that is responsible for its temperature
- 11. when energy is stored and held in readiness
- 15. forces that do not cancel each other out when acting together on a single object
- 18. forces that cancel each other out when acting together on a single object
- 19. speed in a given direction
- 20. increase, decrease or change of direction of an objects motion
- 22. the ability to do work or cause change
- 25. the amount of motion an object has
- 27. An object with mass accelerates when a force acts on it. The greater the mass of
