1. A quantity that can be completely described by a single value.
3. ____ force. A perpendicular force.
5. A force that resists the motion of objects.
9. Perpendicular vectors.
12. The object is this when the net force on an object is zero.
13. ____ constant. The relationship between the forces exerted by a spring and its change in length.
14. ____ friction. Exists when forces are acting to cause an object to move but friction is keeping the object from moving.
16. ____body diagram. A simple diagram showing only the forces acting on a body.
2. A fluid used to reduce friction.
4. ____ of rotation. The line about which an object turns.
6. A quantity that includes both magnitude and direction.
7. ____'s law. States that the force exerted by a spring is proportional to its change in length.
8. The total of all the vectors.
10. A single value (without direction).
11. ____ friction. Present when two objects or surfaces slide across each other.
