Pendulum's
Pendulum Lab
A pendulum is something hanging from a fixed point which, when force is applied, swings back, forth, up, and down due to gravity and inertia (Beynon 1). Pendulums can range in shape, size, and weight. An example of a pendulum can range from a swinging chandelier to a washer tied to some string and hung from the ceiling. Galileo was a famous scientist who studied pendulums. He discovered that the period, or time for one full swing, was always the same on a pendulum no matter what the weight on the end is or how wide the swing. He found that the only factor that affected the period was the length of the pendulum (Fleisher 18-20). With this knowledge and some simple equations the acceleration of gravity on Earth can be found.
