Across
- 3. the force that resists motion when the surface of one object comes in contact with the surface of another
- 5. The rate of change of position of an object in any direction
- 8. a physical quantity that is completely described by its magnitude
- 11. forces acting at the same point with equal magnitude but opposite direction, resulting from Newton's third law
- 13. the rate of change of the velocity of an object.
- 14. pair
- 15. the universal force of attraction acting between all matter
- 16. the change of momentum of an object when the object is acted upon by a force for an interval of time.
Down
- 1. a quantity that has both magnitude and direction
- 2. the measure of the amount of matter in a body
- 4. state of rest
- 6. the change in position of an object
- 7. motion of an object thrown (projected) into the air when
- 9. The push or pull on an object with mass causes it to change its velocity
- 10. the sum of all the forces acting on an object
- 12. the product of an object's mass and velocity
