Across
- 2. for every action (force) in nature there is an equal and opposite reaction.
- 3. Displacement = Final position – initial position = change in position.
- 7. rate at which velocity changes with time, in terms of both speed and direction.
- 8. with direction
- 11. Speed with direction
- 12. Newton’s first law
- 14. Force in air
- 16. stored energy that depends upon the relative position of various parts of a system
- 17. the energy an object has because of its motion
- 19. movement
- 20. Distance = time * velocity
Down
- 1. the applied force F equals a constant k times the displacement or change in length x, or F = kx.
- 4. how far an object has moved
- 5. Energy cannot be created or destroyed can only be trabsfered
- 6. no direction
- 9. the ability to do work
- 10. the work done per unit mass that would have to be done by some externally applied force to bring a massive object to that point from some defined position of zero potential, usually infinity
- 13. the resistance that one surface or object encounters when moving over another
- 15. The rate of change of position of an object in any direction
- 18. Newton’s second law
