12. The distance at which an object moves per unit of time.
14. The rubbing of one thing against another
18. The size and direction of a net force equals the mass times acceleration.
19. A place or object used for comparison to determine whether something is in motion

1. When one force is greater than another.
2. The speed at which an object travels in a given direction.
3. A push or a pull.
4. If one object exerts a force on another object, then the second object exerts a force of equal strength in opposite direction on the first object.

6. When the forces on an object are equal and in opposite directions.
9. The resistance to change in motion.
10. The combination of all forces acting on an object.
