6.7 Vocabulary

4. Newton's __________ Law of Motion states that for every force applied to an object, there is a simultaneous force applied that is equal in magnitude and opposite in direction.
7. Illustrates/models the forces acting on an object. Direction of the force is depicted using an arrow. Magnitude of the force may be shown using the size of an arrow or with a numerical label.
9. a push or a pull on an object by another object
11. unit of measurement of force
12. force that occurs between two surfaces (that opposes motion)
13. a force that pulls objects toward each other (the more mass, the greater this force's magnitude is for that particular object)
14. Equal and opposite forces on an object that result in no change in motion The calculated net force is zero.
15. Forces acting in the _______ direction are added.

1. Unequal forces on an object that may result in a change in motion. The calculated net force is not zero.
2. forces between two objects that are not touching are considered forces that act across a ________________
3. Forces acting in __________ directions are subtracted.
5. force that the surfaces of objects apply to each other to prevent them from moving through each other
6. A force that pushes or pulls a magnetic material across a distance
8. Sum of the total forces exerted on an object. Calculated by adding all of the forces acting on an object
10. forces experienced when objects are touching
12. all ________ are described with magnitude (measuring in Newton's) and direction
