Physics

2. The separation between two points.
4. Variable Responding variable.
7. Force Forces that give materials their strength.
11. velocity Velocity measured over a finite time interval.
12. Acceleration Acceleration measured over a finite time interval.
14. third law 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.
16. Ratio of change in position to time interval over which change takes place.
17. Friction Force that opposes the start of motion.

1. Variable The manipulated variable.
3. first law An object with no force acting on it moves with constant velocity.
5. Change in position.
6. Quantity having both magnitude and direction.
8. of Friction A constant that depends on the surfaces in contact.
9. Change in velocity divided by time interval over which it occurred.
10. The force that opposes the motion between two surfaces that are in contact.
13. Gravitational force exerted by a large body, usually Earth.
15. Quantity, like distance, that has only a magnitude, or size.
17. The magnitude of the velocity.
