Newtons laws

4. The acceleration is equal to the net force divided by the mass
5. a force pulling an object to its center
6. The force to objects add to eachother
7. a push or pull on an object that doesnt require an object to touch it
9. The resistance of an object to change motion
10. All of the forces acting on a object combined form a net force of 0
14. strength or energy as an attribute of physical action or movement.
15. any motion that a object moves along a curved path
18. When one object exerts force on a second object, the second object exerts the same amount of force on the first object
19. the amount of gravity exerted on an object

1. If the net force is 0 the motion does not change
2. The total momentum of a group of objects stays the same unless an outside force acts on it
3. a combination of all forces acting on an object
8. A push or pull on an object that is cause by another object that is touching it
11. all of the forces acting on an object combined form a netforce that is not 0
12. the amount of resistence between 2 surfaces
13. an attractive force that pulls all objects that have mass
16. The amount of matter in an object
17. A measure of how hard it is to stop an object
