3. Law that states that the acceleration of an object is equal to the net force exerted on the object divided by the objects mass.
5. An attractive force that exists between all objects that have mass.
7. Force that one object applies to another object without touching it.
9. Push or pull on objects.
10. In circular motion a force that acts perpendicular to the direction of motion toward the center of the curve.
11. The gravitational force exerted on an object.
12. A contact force that resists the sliding motion of two surfaces that are touching.
15. Any motion in while an object is moving along a curved path.
16. Law that states that if the net force acting on an object is zero the motion of the object does not change.
17. The amount of matter in an object.
18. A measure of how hard it is to stop a moving object.

1. force Push or pull on one object by another object that is touching it.
2. The tendency of an object to resist a change in its motion.
4. Principle stating that the total momentum of a group of objects stays the same unless outside forces act on the object.
6. Law that states that for every action there is an equal and opposite reaction
8. The combination of all the forces acting on an object.
13. Forces acting on an object that combine and form a net force of zero.
14. The force two objects apply to each other.
