Forces and Motion

3. On a velocity-time graph, this describes a flat line — the speed is not changing
6. The force of gravity on something
9. Forces that do not cancel out
12. Friction from moving through the air
14. How quickly velocity changes
15. A push or a pull
16. Newton’s second law written as a short formula
18. On a distance-time graph, this kind of line shows the object is speeding up or slowing down
20. How far something travels
21. On a velocity-time graph, this means the line is going down — the object is slowing down

1. On a distance-time graph, this kind of line means the object is not moving
2. How much matter something has
4. The slope of a graph line
5. The overall force on an object
7. Distance in a straight line with direction
8. Force that slows things down
10. Speed with direction
11. Forces that are equal and cancel out
13. On a distance-time graph, this kind of sloped line means constant speed
14. On a speed-time graph, this shows the distance travelled
17. How fast something is moving
19. On a velocity-time graph, this means the line is going up — the object is getting faster
