science project

1. law that states for every action there is an equal and opposite reaction
3. a contact force that resists the sliding motion of two surfaces that are touching
5. law that states that the acceleration of an object is equal to the net force exerted on the object divided by the objects mass
7. a force on one object applies to another object without touching it
9. a push or pull on an object
10. the tendency of an object to resits a change in its motion
11. the combination of all the forces acting on an object
12. a measure of how hard it is to stop a moving object
14. any motion that in which an object is moving along a curved path
15. forces forces acting on an object that combine and form a net force of zero
16. an attractive force that exists between all objects that have mass

2. the gravitational force exerted on an object
4. the amount of matter in an object
5. law that states that if the net force acting on a object is zero, the motion of the object does not change
6. a push or pull on one object by another object that is touching it
8. the forces that two objects apply to each other
13. in circular motion, a force that acts perpendicular to the direction of motion toward the center of the curve
