Constant Velocity Tubes

Experiment 1

To preserve the “discovery” aspect of the lab, you will need to cover

the ends of the tubes with paper before the lab starts. A sheet of notebook

paper secured with rubber bands and masking tape works well. Scotch (or

cellophane) tape is very difficult to remove from the tubes.

7. Red or violet tube:

1 cm

Orange or blue tube:

9 cm

Yellow or green tube:

16 cm

8. The y-intercept is the position of the bubble at time = 0; more simply, it is the initial

position of the bubble.

9. The measurement should be approximately the same value as the value at the y-intercept.

10. The answers to 7 and 9 should be approximately the same.

11.

12. The result should be two parallel lines having the same slope but different y-intercepts.

The difference in y-intercepts is due to the different initial positions.

13. See graph above.
