Across
- 4. the motion of an object where the only force acting on it is gravity
- 5. a coordinate system or viewpoint used by an observer to make measurements of an object's position, velocity, and other physical quantities
- 6. a push or pull on an object that can cause it to change its velocity or shape
- 7. rate of change of an object's position with direction
- 8. the total length of the path traveled by an object
- 11. the change in position of an object
- 13. a force that opposes the relative motion or attempted motion between two surfaces in contact
Down
- 1. the rate at which velocity changes over time
- 2. quantity with magnitude but no direction
- 3. the force exerted by air that opposes the motion of an object moving through it
- 9. the rate at which an object covers distance, or the distance traveled per unit of time
- 10. quantity that has both magnitude and direction
- 12. universal force of attraction that exists between all objects with mass or energy, pulling them toward one another
