Across
- 6. (five words) The acceleration of an object is equal to the net force acting on the object divided by the object's mass.
- 7. is the amount of matter in an object
- 8. attractive force that exists between two objects that have mass
- 10. is the gravitational force exerted on an object
- 12. (five words)the total momentum of a group of objects stays the same unless outside forces act on the objects
- 13. (two words)force that on object applies to another without touching
- 15. (two words) a push or pull on one object by another that is touching
- 16. the tendency of an object to resist change in its motion
- 17. the measure of how hard it is to stop a moving object
Down
- 1. (five words) If the net force on an object is zero, the motion of the object does not change.
- 2. (two words) two forces acting on an object that combine and form a net force that is not zero
- 3. (two words) the forces two objects apply to each other
- 4. (five words) When one object exerts a force on a second object, the second object exerts and equal force in the opposite direction of the first object.
- 5. (two words) two forces acting on an object that combine and form a net force of zero
- 9. a force that resists the motion of two surfaces that are touching
- 11. (two words) the combination of all the forces acting on an object
- 14. push or pull on an object
