Across
- 2. a push or a pull
- 9. states that the acceleration of an object increases with increased force and decreases with increased mass
- 10. is a measure of how fast something moves or the distance it moves
- 11. a location to which you compare other locations
- 12. force the overall force acting on an object when all the forces are combined
- 13. a force that resist the motion between two surfaces in contact
- 14. differs from the friction between solid surfaces
- 18. is a speed in a specific direction
- 20. states that every time one object exerts a force on another object , the second object exerts a force that is equal in size and opposite in direction back on the first object
Down
- 1. states that object at rest remain in rest, and object in motion stays in motion
- 3. any force that keeps an object moving in a circle
- 4. is the measure of mass in motion
- 5. the measure of how quickly the velocity is changing
- 6. states that the total momentum of a system of objects does not change as long as no outside forces are acting upon that system
- 7. is a measure of how much force is acting on a certain area
- 8. is a quantity that has both size and direction
- 15. a situation in which two objects in close contact exchange energy and momentum
- 16. is the change of position over time
- 17. the resistance of an object to a change in a speed or the direction of its motion
- 19. a place or an object is the location of that place or object
