Across
- 2. of conservation of momentum, A principle stating that the total momentum of a group of objects stays the same unless outside force acts on the objects
- 4. A contact force that resists the sliding motion of two surfaces that are touching
- 5. Contact Force, A force that one object applies to another object without touching it
- 6. The tendency of an object to resist a change in its motion
- 7. Forces, Forces acting on an object that combine and form a net force of zero
- 9. The gravitational force exerted on an object
- 10. A push or pull on a object
- 13. force, in circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve
- 15. Force, The combination of all the forces acting on an object
- 16. second law of motion, 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
- 17. The amount of matter in an object
- 18. A measure of how hard it is two stop of moving object
Down
- 1. An attractive force that exists between all objects that have mass
- 3. Force, A push or pull on one object by another object that is touching it
- 4. pair, The forces two objects apply to each other
- 8. First Law of Motion, law that states that if net force acting on an object is zero, the motion of the object does not change
- 11. motion, any motion in which a object is moving along a curved path
- 12. third law of motion, law that states that for every action there is an equal and opposite reaction
- 14. Forces, Forces acting on an object that combine and form a net force that is not zero
