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