Across
- 2. An object that goes through a liquid or gas
- 3. A net force acting on an object causes the object to accelerate in the direction of the force
- 5. When 2 or more forces act on a object at the same time.
- 13. includes direction;speed doesn't count.
- 14. Tendency of an object to resist any change in its position
- 17. Friction-like force that opposes motion of objects that move through air
- 19. Units of force
- 20. Force
Down
- 1. When 2 objects go past one another
- 4. Speed
- 6. Static, Sliding, Rolling, Fluid
- 7. When 2 surfaces don't pass one another
- 8. The surface the object rolls on and the rolling object
- 9. Momentum
- 10. Rate of change in velocity
- 11. The force that opposes the sliding motion of 2 touching surfaces
- 12. For every action there is an equal and opposite reaction
- 15. Friction caused by microscopic bumps on surfaces
- 16. How far an object travels
- 18. An object stay in motion stays in motion, or an object at rest stays at rest until a unbalanced net force act upon it
