Across
  1. 1. the measure of the amount of matter in a body/object/thing
  2. 3. states that for every action there is an equal and opposite reaction
  3. 6. the rate at which velocity changes (speeding up)
  4. 10. energy of an object in motion
  5. 11. Wrote the laws of motion
  6. 13. a property of matter by which it remains at rest or in unchanging motion unless acted on by some external force
  7. 18. the Gravitational force with which the Earth attracts the masses towards its center
  8. 19. the speed of something in a given direction
  9. 20. states that objects in motion will stay in motion and objects at rest will stay at rest, until acted upon by a different force
Down
  1. 2. states that a force is equal to change in momentum per change in time
  2. 4. the opposite of acceleration, reduction in speed
  3. 5. the vector sum of all the forces that act upon an object
  4. 7. the resistance that one surface or object encounters when moving over another
  5. 8. energy held by an object, based on its position
  6. 9. a path for transmitting electric current
  7. 12. the ability to exert a force causing displacement of an object
  8. 14. the force exerted by magnets
  9. 15. the force by which a planet or other body draws objects toward its center
  10. 16. the unit of energy in the International System of Units
