Across
- 4. fall when the only force acted on an object is gravity
- 6. second law the acceleration of an object depends on the mass of the object and the amount of force applied
- 8. of conservation of energy the law that states that energy cannot be created nor destroyed but can be changed from one form to another
- 9. a speed in any direction
- 11. the rate in which the velocity changes
- 12. the product of a body's mass and velocity
- 15. the force between two rubbing surfaces
- 16. an object in motion stays in motion
- 17. point A place used for comparison to determine if something is in motion
- 19. the state in which one objects distance from another is changing
- 21. the capacity of a physical system to do work
Down
- 1. the force that pulls objects towards each other
- 2. energy the mechanical energy that a body has by virtue its position
- 3. velocity the maximum speed possible while free falling
- 5. force forces that produce a nonzero net force
- 7. third law for every action there is an equal opposite reaction
- 10. force equal force acting on an object in different directions
- 13. energy the mechanical energy that a body has by virtue of its motion
- 14. the distance an object travels per unit of time
- 18. push or pull on an object
- 20. force the overall force on an object
