- 3. the net force on an object is zero the motion of an object dose not change
- 6. fores acting on an object that combine and form a net force of zero
- 10. a push or pull on an object
- 11. a masure of how hard it is to stop a moving object
- 12. a force that resists the motion of two surfaces that are touching
- 14. A force that one object can apply to another without touching it
- 15. the gravitational force exerted on an object.
- 16. when one object exerts a force on an second object the second object exerts an equal force in the opposite direction on the first object
Down
- 1. the combination of all the forces acting on an object
- 2. forces acting on an object that combine and form a net force that is not zero
- 4. any motion in wich an object is moving twords the center of the cerve
- 5. the amount of matter in an object.
- 7. an attractive force that exists between all objects that have mass
- 8. a push or pull on one object by another that is touching it.
- 9. in cucular motion a force that acts perpendicular to the direction of motion towords the center of its curve
- 13. the forces two objects apply to eachother
