- 2. forces acting on an object that is combined and from net force that is not a zero
- 3. a measure of how hard it is to stop moving objects
- 6. a push or a pull on one object by another object that is touching.
- 7. A high-energy electromagnetic wave with a shorter wave length and higher frequency than all other types of electromagnetic waves.
- 8. the amount of matter in an object.
- 11. the forces two objects apply to each other.
- 13. the combination of all the forces acting on an object
- 14. in circular motion, a force that acts perpendicular to the direction of motion, towards the direction of motion, toward the center of the cure.
- 15. a principle stating that the total momentum of a group of objects stays the same unless outside forces act on the objects.
- 16. A constant force that resists the sliding motion of the surfaces that were touching.
Down
- 1. law that states that the acceleration of an object is equal to the net forces exerted on the object divided on the object t divided by the objects mass.
- 4. law that states that for every action there is an equal and opposites reaction.
- 5. The gravitation force exerted on an object
- 9. elements, including iron, Nickle, and cobalt, that have an especially strong attraction to magnets.
- 10. a force that on object applies to another object without touching it.
- 12. Any motion in which an object is moving along & curved path.
