Across
  1. 3. A pulling force that works across space.
  2. 6. A force that one surface or object encounters when moving over another; it is a resistance to motion.
  3. 7. A change in position over time.
  4. 8. The distance an object travels per unit of time.
  5. 9. The relationship between speed and direction of a moving object.
  6. 10. The result of a force.
  7. 11. Forces acting on an object that combine and form a net force that is not zero; object will change direction, speed up or slow down, stop, start moving.
  8. 14. The combined forces acting on an object.
  9. 15. The force or speed with which something moves; the more mass, the more momentum.
  10. 17. For every action there is an equal and opposite reaction.
  11. 19. If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.
  12. 20. The tendency of an object to resist a change in motion.
Down
  1. 1. Forces acting on an object that combine and form a net force of zero; object will stay still or move at the same speed and going in the same direction.
  2. 2. English mathematician and scientist who defined the laws of motion and gravity. Tried to explain motion of the universe.
  3. 4. A push or pull exerted on an object.
  4. 5. The acceleration of an object depends on the mass of the object and the amount of force applied.
  5. 12. Force = mass x acceleration
  6. 13. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
  7. 16. The rate at which velocity (speed and direction) changes (speed up or slow down).
  8. 18. A measure of the amount of matter in an object.
