Across
- 1. The separation between two points.
- 2. Study of matter and energy and their relationships.
- 3. 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.
- 4. A constant that depends on the surfaces in contact.
- 9. Ratio of change in position to time interval over which change takes place.
- 11. Gravitational force exerted by a large body, usually Earth.
- 13. Force that opposes the start of motion.
- 14. Change in velocity divided by time interval over which it occurred.
- 16. The acceleration of a body is directly proportional to the net force on it and inversely proportional to its mass.
Down
- 1. Responding variable.
- 5. Forces that give materials their strength.
- 6. The manipulated variable.
- 7. The force that opposes the motion between two surfaces that are in contact.
- 8. An object with no force acting on it moves with constant velocity.
- 10. Change in position.
- 12. The magnitude of the velocity.
- 15. Quantity having both magnitude and direction.
- 17. Quantity,like distance,that has only a magnitude, or size.
