Constant Velocity Tubes

14. A greater slope corresponds to a greater speed.

15. The slopes (speeds) will vary depending on room temperature. Typical values might be:

red, orange, yellow tubes:

5.4 cm/s

green, blue, violet tubes:

3.8 cm/s

16. a) Greater slope corresponds to greater speed.

b) The dimensional units of the slope are appropriate for speed (velocity).

c)

The rise is the change in position during a time interval, and the run is the elapsed

time during that time interval. Rise divided by run equals the average speed

(velocity).

17. for example, green: position = 3.8 cm/s • time + 16 cm

18. position = velocity • time + initial position
