Forces and Motion
Across
- 2. a force that acts between any two masses.
- 3. the friction force that acts on objects that are not moving.
- 7. the friction force that acts on rolling objects.
- 9. the overall force acting on an object after all the forces are combined.
- 10. the distance an object travels divided by the time it took to get there
- 13. a force that opposes the direction of motion of an object as it slides over a surface.
- 14. a measure of the inertia of an object.
- 16. the length between a start point and end point with a direction
- 18. a force that opposes the motion of objects that touch as they move past each other.
- 19. the tendency of an object to resist a change in its motion.
Down
- 1. fluid friction acting on an object moving through the air
- 4. are forces that combine to produce a net force of zero.
- 5. the force of gravity acting on an object.
- 6. the motion of a falling object (projectile) after it is given an initial forward velocity.
- 8. a push or a pull that acts on an object.
- 11. the length between two points
- 12. a force that results when the net force acting on an object is not equal to zero.
- 15. (N) is the unit of measure for force
- 17. is the constant velocity of a falling object when the force of air resistance equals the force of gravity.
- 18. opposes the motion of an object through a fluid.
