Across
- 1. exists when an object from the external world touches a system exerting force on it
- 6. a specific name for the force that a string or rope exerts
- 10. vector quantity that relates the mass of an object to the gravitational force it experiences at a given location
- 14. a push or pull
- 15. set of two forces that are in opposite directions, have equal magnitudes, and act on different objects
- 16. important objects of interest with respect to how the force affects motion
- 17. a physical representation that shows the forces acting on a system
Down
- 2. the constant velocity that is reached when the drag force equals the force of gravity
- 3. the vector sum (could be adding or subtracting)of all the forces on an object
- 4. the gravitational force experienced by that object
- 5. the force exerted by a fluid on an object opposing motion through fluid
- 7. acceleration is proportional to the net force and inversly proportional to the mass of the object being accelerated
- 8. the normal force exerted by a surface on an object, which can differ from the objects true weight due to acceleration
- 9. an object at rest will stay at rest ect.
- 11. the perpendicular contact force that a surface exerts on another surface
- 12. if the net force on an object is zero
- 13. forces exerted without touching
- 15. the tendency of an object to resist change in velocity
