recoeded the data in data table. Part II Length 7. In this part, we used the 200-g mass and a consistent amplitude of 20º for each trial. We have changed the pendulum length in steps of 10 cm, from 1.0 m to 0.50 m. then repeated Step 5 for each length. Recorded the data in the second data table below. Then measured the pendulum length from the rod to the middle of the mass. Physics with Computers 10 - 2
Pendulum Periods Part III Mass 8. we have used three masses to determine if the period is affected by changing the mass. We measured the period of the pendulum with different masses, keeping the distance from the ring stand rod to the center of the mass the same each time, as well as keeping the amplitude the same. We repeated Step 5 for each mass, using an amplitude of about 20°and recorded the data in data table.

Why is Logger Pro set up to report the time between every other blocking of the Photogate? Why not the time between every block?
Pendulum Periods graph. This means measuring the time lapse between two points in the motion where the displacement and the direction of motion is the same. Since it is generally not possible to get the position of the photogate exactly at the equilibrium of the motion we take the elapsed time between crossings in the same direction, otherwise one would get a sort of half period (a little under or over) value.
