Across
- 4. The rate at which velocity changes with time; the change may be in magnitude or direction or both.
- 8. When two values change in opposite directions, so that if one increases and the other decreases by the same amount.
- 11. The property of things to resist changes in motion.
- 12. The acceleration produced by a net force on an object is directly proportional to the net force, is in the same direction as the net force, and is inversely proportional to the mass of an object.
Down
- 1. The quantity of space an object occupies
- 2. The quantity of matter in an object.
- 3. Terminal speed with direction of motion (down for falling objects).
- 5. Motion under the influence of gravitational pull only.
- 6. The force due to gravity on an object.
- 7. The speed at which the acceleration of a falling object terminates because air resistance balances its weight.
- 9. The resistive force that opposes the motion or attempted motion of an object past another with which it is in contact, or through a fluid.
- 10. The fundamental SI unit of mass.
- 13. Frictional resistance due to motion through the air.
