Physical Pendulum Lab

1. meterstick

2. three large binder clips

3. spinner

4. ring stand

5. 90 degree clamp.

6. tape

Each Team will be given the:

1. number of clips to attached to their ruler.

2. lab sheet

IMPORTANT - The ruler is oriented such that 0 cm is nearest the ceiling; 100 cm is nearest the floor.

After you have calculated your period, assemble your apparatus.

4. Calculate the period of your physical pendulum.
NOTE - The mass (moment of inertia) of the spinner is negligible.

5. If your teacher allows, secure the pendulum hanger to the ring stand as shown below.

6. Secure your ruler to the pendulum hanger with two pieces of tape as shown. The pivot point should align with center of the pendulum hanger and located between the 20 and 30 cm position.

Remember - The ruler is oriented such that 0 cm is nearest the ceiling; 100 cm is nearest the floor.

7. Secure each clip to the ruler at its selected position. Secure clips such that the center of the clip aligns with its position. See example shown for position 20 cm.

• One clamp in placed above the pivot point
• Two clamps are placed below the pivot point and at least 25 cm apart.

8. Call your teacher over or bring your pendulum to your teacher to measure your pendulum with a motion detector.
