Describe your observations of the sounds made as the sphere crosses the unequally spaced rubber bands (procedure Step 9)? (Use same angle as Step 4.)

ive included the lab information in case it would provide better context.

Lab Information

Activity 5: Demonstrate that a sphere rolling down the incline is moving under constant acceleration

1. Collect the piece of foam board. Use a ruler and a pencil to draw lines across the short dimension (width) of the board at 5 cm increments.

2. Collect rubber bands from the central materials kit. Wrap the rubber bands around the width of the foam board so that the rubber bands line up with the pencil marks you made at the 5 cm intervals. See Figure 10, left panel.

3. Use a book to prop up the foam board as an inclined plane at an angle from 5 to 10 from the horizontal.

4. Place the steel sphere at the top of the ramp and allow the sphere to roll down the foam board.

5. Remove the rubber bands from the foam board.

6. On the reverse side of the foam board, use a pencil to mark a line across the short dimension of the board 2 cm from the end. Label this line zero.

7.Mark lines at the distances listed in Table 5. Each measurement should be made from the zero line.

Place rubber bands on the foam board, covering the pencil lines you just made.

8. Set the foam board up at the same angle as the previous trial.

9. Roll the steel sphere down the foam board.

Note: The sound as the steel sphere crosses the rubber bands will increase in frequency as the steel sphere rolls down the ramp, indicating that the sphere is accelerating. As the sphere continues to roll down the incline, it takes less time to travel the same distance.

If the steel sphere is moving under a constant acceleration, then the displacement of the sphere from the initial position, if the sphere is released from rest, is given by: = (1/2 ) ^2

The displacement at each time t should be proportional to ^2

Note: The sounds made as the sphere crosses the rubber bands on the foam board in the second trial should be at equal intervals. The sphere is traveling a greater distance each time it crosses a rubber band, but the time interval remains constant meaning the sphere is moving with a constant acceleration.
