- 4. Forces acting on an object that combine and form a net force of zero
- 6. Any motion in which an object is moving in a curved path
- 8. A measure of hard it is to stop a moving object
- 9. The combination of all the forces acting on a object
- 11. A push or pull on a object
- 12. Law that states for every action there is an equal opposite reaction
- 13. A principle stating that the total momentum of a group of object stay the same unless an outside force act on objects
- 15. A contact force that resists the sliding motion of two surfaces that are touching
- 17. The forces two objects apply to each other
- 18. Law that states if the net force acting on an object is zero the motion of an object does not change
Down
- 1. The tendency of an object to resist a change in its motion
- 2. In circular motion a force that acts perpendicular to the direction of motion towards the center of the curve
- 3. An attractive force that exist between all objects that have mass
- 5. A push or pull on one object by another object that is touching it
- 7. law that states that the acceleration of an object is equal to the net force on an object divided by the object's mass
