physical science module 2
Across
- 1. the constant velocity of a falling object when air resistance equals the force of gravity.
- 5. measurement of how much an object has moved.
- 7. Friction friction force that acts on rolling objects
- 8. velocity that does not change.
- 10. speed the distance divided by the elapsed time.
- 13. the change of an object’s velocity over time.
- 14. Friction force that acts on objects that are not moving. (Couch Potato)
- 17. the product of an object’s mass and its velocity.
- 18. movement in relation (or relative) to a frame of reference
- 20. the speed & direction an object is moving
- 21. force that opposes motion between 2 surfaces
Down
- 2. a quantity that has magnitude & direction
- 3. are quantities that are fully described by a magnitude (or numerical value) alone.
- 4. measurement of how distance and direction has changed.
- 6. speed measured at a particular instant
- 9. Friction force that opposes the direction of motion of an object as it slides over a surface. (Ice skating or bobsledding)
- 11. speed computed for the entire duration of the trip
- 12. of reference system of objects that are not moving with respect to one another
- 15. force unbalanced forces that are not opposite and equal
- 16. Unit is meter per second
- 19. a change in position
