Across
- 1. How fast an object is moving, regardless of direction. (Shown by the slope on a distance-time graph.)
- 4. When gravity is the only force acting on an object. (Objects in this state accelerate at 9.8 m/s².) (4,4)
- 7. Forces that do not cancel out, causing acceleration.
- 10. Speed with a specified direction.
- 11. Forces that cancel out, resulting in no change in motion.
- 12. The force that pulls objects toward Earth.
- 13. A push or pull that causes a change in motion.
- 14. A quantity with both magnitude and direction, like displacement or velocity.
Down
- 1. When an object is not moving at all. (A flat horizontal line on a distance-time graph.)
- 2. The shortest distance from start to finish with direction. (Can be zero even if you’ve traveled a long way!)
- 3. The force of gravity on an object’s mass.
- 5. Another way to describe constant motion.
- 6. The overall effect of combining multiple forces.
- 8. The rate of change of velocity. (A curved line on a speed-time graph means this is changing.)
- 9. The total length of the path taken, always positive.
- 15. Unchanging; can describe speed, velocity, or acceleration.
