Across
- 5. the way the force is moving
- 8. A balanced net force equals this.
- 10. two or more unequal forces that cause an object to start, stop, or change direction in motion.
- 12. force that resists the start of sliding motion between two surfaces that are touching
- 13. a contact force between two surfaces
- 14. when gravity is pulling an object down and no other forces are acting on it
- 15. the change in distance and velocity over time
- 17. unit to express force (N)
- 19. a force of attraction between objects due to their mass
- 20. the measure of motion and change in distance over time
Down
- 1. equal forces acting on an object in opposite direction
- 2. strength
- 3. friction-like force that opposes the motion of an object in a fluid
- 4. the force that resists the movement of two surfaces that are touching and are moving relative to each other
- 6. an object’s tendency to resist a change in motion
- 7. the combination of all the forces acting on an object
- 9. when an object travels around another object in space
- 11. the change in speed or velocity over time
- 16. a push or a pull
- 18. the area in which an object experiences force
