Chapter 12 Forces & Motion Vocabulary
Across
- 2. force the overall force acting on an object after all the forces are combined
- 4. a friction force that opposes the motion of an object as it slides over a surface
- 7. the tendency of an object to resist a change in its motion
- 8. the force of gravity acting on an object
- 11. the curved path of an object in free fall after it is given an initial forward velocity
- 12. the amount of matter in an object
- 14. resistance fluid friction acting on an object moving through the air
- 15. a friction force that acts on objects that are not moving
- 16. a friction force that acts on rolling objects, caused by the change in shape at the point of rolling contact
- 17. a push or pull that acts on an object
- 18. the SI unit for force
Down
- 1. a force that continuously changes the direction of an object to make it move in a circle
- 3. the product of an object's mass and velocity
- 5. the attraction between any two objects because of their masses
- 6. a force associated with charged particles
- 9. the constant velocity of a falling object when the force of air resistance equals the force of gravity
- 10. a substance or mixture that flows and has no shape of its own
- 13. a force that opposes the motion of objects that touch as they move past each other
