Restoring force on a displaced pendulum
Article no. P1000200 | Type: Experiments
The students should measure the restoring force F of a deflected pendulum as a function of the deflection x for two different pendulum lengths.
Additionally, they should calculate the ratios x / l and F / Fg and compare them with each other. From the force parallelogram on the deflected pendulum they should conclude that these ratios are nearly equal.
