  1. 3. Measure of an amount of atoms (matter) in something (kg).
  2. 5. Force: Sum of all forces acting on an object (N).
  3. 7. The rate at which work is done (W).
  4. 8. Force: The force that the machine exerts on an object.
  5. 9. Advantage: The number of times a machine increases a force exerted on it.
  6. 12. Speed in a given direction (m/s + direction).
  7. 15. The force that attracts objects towards another object (N).
  8. 16. The percentage of the input work that is converted into output work, the higher the percentage, the more efficient the machine.
  9. 18. A measure of the force of gravity on an object (N),

  1. 1. Exerting a force on an object that causes the object to move some distance (J).
  2. 2. Force: The force the machine exerts on an object.
  3. 4. A change in velocity or direction (m/s2).
  4. 6. A force that acts in an opposite direction to movement.
  5. 9. Found in a moving object, mass*velocity, p=m*v (kgm/s).
  6. 10. Third Law: Every action has an equal and opposite reaction, forces come in pairs known as the action/reaction pair.
  7. 11. Distance an object travels per unit of time (m/s2).
  8. 13. Property of an object that causes it resist a change in its motion.
  9. 14. A device that allows you to do work in a way that is easier or more effective.
  10. 17. A push or pull.
