Newtons laws

4. The forces two objects apply to each other.
5. In circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve is centripetal force.
8. collision where objects bounce off each other
9. a force that resists the motion of two surfaces that are touching
11. When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction of the first object.
12. any motion in which an object is moving along a curved path.
13. the tendency of an object to resist a change in its motion

1. is a measure of how hard it is to stop a moving object.
2. an attractive force that exists between all objects that have mass
3. The acceleration of an object is equal to the net force acting on the object divided by the object’s mass
4. A push or a pull
6. collision where objects stick together
7. speed in a certain direction
10. the amount of matter in an object
