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. Materials

5 different pendulums with different lengths, stopwatch, meter stick Procedure
Start each pendulum from approximately 10°
Let the pendulum go for 10 full swings
Time dhow long the 10 swings took and divide this time by 10 to get the period Repeat this same procedure 3 times on 5 different pendulums. With proper measurements and times a relative acceleration can be found for the gravity of Earth. Though calculations are difficult to be exact because of the effects of human error and air friction, they are relatively close to the accepted value of 9.8 m/s². The pendulum became a way to not only develop a more sophisticated clock but also as a proof of the rotation of the planet Earth. Works Cited

...Performing the real lab:
* The compound bar pendulum AB is suspended by passing a knife edge through the first hole at the end A. The pendulum is pulled aside through a small angle and released, whereupon it oscillates in a vertical plane with a small amplitude. The time for 10 oscillations is measured. From this the period T of oscillation of the pendulum is determined.

Title: Determination of the acceleration due to gravity with a simple pendulum
Introduction and Theory: A simple pendulum performs simple harmonic motion, i.e. its periodic motion is defined by an acceleration that is proportional to its displacement and directed towards the centre of motion. It can be shown that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: T2=...

...Pendula
A pendulum consists of an arm of low mass with a bob, which has a higher mass, on the end. The top of the arm is pivoted so that the pendulum can swing. A pendulum will continue to swing back and forth indefinately, until it is stopped by air friction and friction within the pivot. When the angle, á, between the stationary line of the pendulum (the line towards which the movement tends) and the line of maximum amplitude of the...
