Across
- 1. rate of change of velocity over time
- 4. international unit of measure for force
- 11. change in position overtime
- 12. Two unequal forces causing a change
- 14. a force that keeps an object at rest.
- 15. speed with direction
- 16. Object at rest stay at rest until acted upon
- 18. A force that resists the motion of two surfaces that are touching
- 19. distance over time
Down
- 2. F=m x a
- 3. the friction between layers of a viscous fluid that are moving relative to each other
- 5. type of friction that occurs when a wheel, ball, or cylinder rolls freely over a surface.
- 6. Two equal forces acting in opposite
- 7. Force vary action there is an equal and opposite reaction
- 8. mass in motion must times velocity
- 9. is an attractive force that exists between all objects that have mass
- 10. a property of matter by which it remains at rest or in unchanging motion unless acted on by some external force.
- 13. A push or a pull
- 17. the combined effect (the sum) of all the pushing and pulling forces actually acting on the object.
- 20. where someone or something is located
