2. the force of attraction between all masses in the universe.
6. the capacity for doing work.
7. something that causes a change in the motion of an object.
8. the branch of mechanics that deals with the actions of forces in producing or changing the motion of masses.
9. a physical vector quantity; both magnitude and direction are needed to define it.
10. occurs when there is no force of support on your body.
13. existing and ready for action, but not active.
15. the property of matter that measures its resistance to acceleration.

1. is done when a force that is applied to an object moves that object.
3. the resistance of any physical object to any change in its state of motion including changes to its speed and direction or the state of rest.
4. the force exerted by a surface as an object moves across it or makes an effort to move across it.
5. a vector quantity that is defined as the rate at which an object changes its velocity.
10. the force exerted on a body by gravity.
11. the property or tendency of a moving object to continue moving.
12. being or situated at right angles to the horizon; upright.
