A swinging chandelier in a cathedral got Galileo thinking about the motion of pendulums, which led to the experiments he conducted while at the University of Pisa.
Experiment with a pendulum. See how changing its weight, the height of release, and its length affects its period (how fast it makes one complete swing).
Which of the following statements is true?
changing the bob's weight changes the pendulum's period
changing the release height changes the pendulum's period
changing the length changes the pendulum's period
