8.6 CW 1
Across
- 5. a change in position of an object over time
- 6. a drawing that uses arrows to represent the forces acting on an object
- 9. how fast an object moves
- 11. not moving relative to a reference point
- 12. the tendency of an object to resist changes in its motion
- 14. forces acting on an object that do not cancel out, resulting in a nonzero net force
- 16. motion in which an object changes direction and follows a circular or curved trajectory
- 19. the curved path of an object moving around a center due to a force acting toward that center
- 20. forces acting on an object that are equal in strength and opposite in direction, resulting in a net force of zero
- 21. the support force exerted by a surface on an object in contact with it
- 22. a force exerted by a stretched or compressed object that tries to return to its original shape
- 24. a push or pull that can change an object’s motion
- 26. a quantity that has both magnitude and direction
- 27. speed in a given direction
Down
- 1. a fixed point or object used to determine an object’s position and motion
- 2. the strength or size of a force
- 3. the force that opposes motion between two surfaces that are sliding past each other
- 4. a force that is exerted on an object by a person or another object
- 7. a place or object used for comparison to determine if something is moving
- 8. a net force that is not equal to zero and causes a change in motion
- 10. the way an object is moving
- 13. a single object shown in a force diagram with all forces acting on it
- 15. the total force acting on an object after all forces are added together
- 17. the location of an object relative to a reference point
- 18. motion described based on the observer’s frame of reference
- 23. a force that opposes motion when an object moves through a fluid such as air or water
- 24. a force that opposes motion between two surfaces in contact
- 25. the force of attraction between Earth and objects with mass
