- 3. the friction in-between sliding and rolling objects
- 4. object falling due to gravity
- 5. the constant speed that a freely falling object eventually reaches
- 9. How much force is needed to change the direction of a 1 kg object
- 11. created to provide controlled amounts of force
- 14. The amount of friction a surface has against an object
- 15. a force that opposes and reduces motion on a large and microscopic scale
- 17. happens when 2 surfaces could move relative to each other but are not yet moving
- 19. if you deform an ideal spring twice as far, it will produce twice the force
