Forces & Motion Vocabulary

7. the speed and the direction of a moving object.
8. a region of space that has a physical quantity (such as a force) at every point.
12. an object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object.
15. a push or a pull on an object.
16. a push or a pull on one object by another object that is touching it.
17. a measure of the distance an object travels in a given amount of time.

1. law that states that the acceleration of an object is equal to the net force exerted on the object divided by the object’s mass.
2. a force that one object applies to another object without touching it.
3. contact force that resists the sliding motion of two surfaces that are touching.
4. a measure of the change in velocity during a period of time.
5. when colliding objects bounce off each other.
6. a simple model to understand what will happen to an object due to a force.
9. when an object applies a force on another object, the second object applies a force of the same strength on the first object but the force is in the opposite direction.
