Steps 1. Make a pendulum by attaching a mass to the end of a string of length 1 meter. 2. Pull the pendulum about 10 centimeters back from its rest position. 3. Release the pendulum. Let it swing for 10 seconds, counting the number of back-and-forth swings. 4. Determine the time per swing, which is the period. Your result should be a measured period of about 2 seconds. Write the results of your measurements. 5. Repeat steps 2-4, but starting this time with initial amplitude of about 20 centimeters from the rest position. The period should be very similar to before since it does not depend on amplitude. Write the results of your measurements. 6. Repeat steps 1-4, but using a different mass (lighter or heavier). The period should remain similar since it does not depend on mass. Write the results of your measurements. 7. Repeat steps 1-4, but now with a different length pendulum. Shorten the length to 25 cm instead of 1 meter. The resulting period should be about half as long = 1 second. Test this prediction
