  1. 3. The tendency of an object to resist a change in motion.
  2. 9. The combination of all forces acting on an object.
  3. 10. Force equals mass times acceleration.
  4. 13. A push or a pull.
  5. 14. 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.
  6. 15. Forces acting on an object that combine and form a net force that is not zero.
  7. 16. A force that opposes motion between two surfaces that are in contact.
  8. 17. The distance an object travels per unit of time.

  1. 1. For every action there is an equal and opposite reaction.
  2. 2. The amount of matter in an object.
  3. 4. A measure of the gravitational force exerted on an object.
  4. 5. Rate of change of velocity.
  5. 6. The speed of an object in a particular direction.
  6. 7. Any two masses exert an attractive force on each other.
  7. 8. Equal forces acting on an object in opposite directions.
  8. 11. The product of an object's mass and velocity.
  9. 12. Total distance divided by total time.
