Unit 10: Forces & Motion
Across
- 5. The ability to do work
- 7. The sum of all forces acting on an object
- 9. An object at rest or at constant speed will stay so unless an unbalanced force is exerted
- 10. The upward force exerted on an object by a surface to support the wight
- 11. Distance/time. Measures how fast an object is going
- 14. Equal forces acting in the opposite direction (net force = N)
- 15. It describes how steep or flat a line is.
- 17. Energy of motion
- 20. The force of gravity
- 21. The force of an engine to move
- 22. Describes something that doesn't move
- 24. A push or a pull
- 25. Where an object is
Down
- 1. The rate at which velocity or speed changes
- 2. Describes something that stays the same (doesn't change)
- 3. Unequal forces acting in different directions (net force > 0)
- 4. Force = mass x acceleration
- 6. For every action, there is an equal & opposite reaction
- 8. Energy that is stored because of an object's position
- 12. The path that an object follows
- 13. The amount of matter in an object
- 15. It pulls things towards the centre of the Earth or another huge object
- 16. Force that opposes motion of objects through air
- 18. Change in position
- 19. The speed and direction of an object
- 23. A surface force that opposes motion to slow it down or stop it
