  3. 9. it is the tendency to resist changes
  4. 12. The size of a physical quantity (used for scalars)
  5. 13. it indicates the amount of particles in an object (it never changes)
  6. 14. "for every action, there is an equal and opposite reaction)
  7. 18. it is a negative or positive change in velocity/time
  8. 20. the force acting on an object due to gravity
  9. 21. it is a turning effect of a force
  10. 22. it is the concept from which the force formula was found out
  11. 24. measurement which has a direction

  1. 1. how far away a body is from its original starting point
  2. 2. thank apples for his discoveries
  3. 4. it describes how fast something is moving
  4. 6. it is a measure of how difficult it is to stop a moving object
  5. 7. measurement of how far apart objects or points are
  6. 8. it shows how fast a body is moving with a given direction
  7. 10. They indicate the direction in which force is acting
  8. 11. Force which tries to prevent two surfaces in contact from sliding over each other (it acts in the opposite direction)
  9. 15. the force of attraction between masses
  10. 16. distance/...=speed
  11. 17. it is the final velocity minus the initial velocity, expressed with a negative sign
  12. 19. it is also known as the law of inertia
  13. 23. something measured with numbers and does not have a direction (only has a magnitude or size)
