Across
- 5. a line that touches another at exactly one point
- 8. speed at a specific instant in time
- 10. the change in position of an object against a fixed axis
- 11. the study of motion without considering its causes
- 13. a quantity that has both magnitude and direction
- 14. the location of an object at any particular time
- 15. a quantity that has magnitude but no direction
- 16. the speed and direction of an object
- 17. a coordinate system from which the positions of objects are described
- 18. velocity at a specific instant in time
Down
- 1. size or amount
- 2. distance traveled divided by time during which motion occurs
- 3. displacement divided by time over which displacement occurs
- 4. the rate at which velocity changes
- 6. the variable, usually along the horizontal axis of a graph, that does not change based on human or experimental action; in physics this is usually time
- 7. rate at which an object changes its location
- 9. the variable that changes as the independent variable changes
- 12. the length of the path actually traveled between an initial and a final position
