Across
- 2. is the number of times a machine multiplies the effort force
- 3. the tendency of an object to resist a change in motion
- 6. states that the acceleration, a, of an object is directly related to the net force, F, applied to the object and inversely related to the mass, m, of the object
- 8. occurs when the force of air resistance becomes large enough to balances the force of gravity
- 10. the amount of matter in an object
- 14. work against motion
- 15. the force exerted by the machine
- 17. is the transfer of energy when an applied force moves an object over a distance
- 18. the force applied to a simple machine
- 19. the force due to gravity-Equal to the product of the object's mass and the acceleration of gravity (w = mg)
- 21. states that an object at rest will stay at rest unless it is acted upon by an unbalanced force
- 22. forces that are opposite in direction and equal in size, cause no change in motion, and the net force equals 0.
- 23. is found by dividing the change in the velocity of the object by the change in time
Down
- 1. is a force between any two objects
- 4. the unit used to measure force
- 5. forces that are not opposite and equal.
- 6. machines that work with one movement
- 7. the act or process of changing position or place
- 9. a measure of speed in a given direction
- 11. an action that can change the motion of an object
- 12. the combination of all of the forces acting on an object.
- 13. the unit used to measure work
- 16. the distance an object moves per unit of time
- 20. states that forces occur as equal and opposite pairs
