2. A measure of the gravitational force exerted on an object.
5. a force that acts perpendicular to the direction of motion, toward the center of the curve
6. The amount of matter in an object
7. A force of attraction between objects that is due to their masses.
10. the forces two objects apply to each other
11. a push or pull on one object by another that is touching it
13. A force that opposes motion between two surfaces that are in contact
14. The combination of all forces acting on an object
17. if the net force on an object is zero, the motion of the object does not change
18. the total momentum of a group of objects stays the same unless outside forces act on the object

1. the accelerations of an object is equal to the net force acting on the object divided by the objects mass
3. when one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object
4. forces acting on an object that combine and form a net force that is not zero
8. forces acting on an object that combine and form a net force of zero
9. is any motion in which an object is moving along a curved path
12. a force that one object can apply to another object without touching it
15. The tendency of an object to resist a change in motion
16. a push or pull on an object
