Physics

2. Quantity having both magnitude and direction.
5. Forces that give materials their strength.
8. The manipulated variable.
10. Responding variable.
13. An object with no force acting on it moves with constant velocity.
17. The force that opposes the motion between two surfaces that are in contact.
18. Change in position.

1. Change in velocity divided by time interval over which it occurred.
3. A constant that depends on the surfaces in contact.
4. Study of matter and energy and their relationships.
6. Ratio of change in position to time interval over which change takes place.
7. Friction Force that opposes the start of motion.
9. The acceleration of a body is directly proportional to the net force on it and inversely proportional to its mass.
11. When one object exerts a force on a second object, the second exerts a force on the first that is equal in magnitude but opposite in direction.
12. Gravitational force exerted by a large body, usually Earth.
14. Quantity,like distance,that has only a magnitude, or size.
15. The magnitude of the velocity.
16. The separation between two points.
