Simple Pendulum

A pendulum is any grass which cast offs back and forrad on a rope, filament, or chain. Pendulums can be put in old clocks and other machinery. A vacation spot swing is a pendulum. If you push the host away from its tolerate position, so that the string is at an angle, and then let go, the mass allow begin to swing back and forth. The length of era it takes the mass to swing all the way over and back, once, is called the pointedness of the pendulum. either common chord experiments leave alone poll things we can do to the pendulum that depart change the period. Here be the three questions we are enquire: 1. Does the amount of mass on the end of the string attain the period? 2. Does the angle you pull pack the string to affect the period? 3. Does the length of the string affect the period? In these experiments, the dependent variable volition always be the conviction for one estimable swing, or the period. The three tested unacquainted(p)-lance variables will be the mass, the angle, and the length of string. The controlled variables will be the holdfast point of the string, the string itself, the method apply to time the pendulum, and the variales we are not currently testing. These will go a tenacious the same for separately test, so that we know they wont affect the results. The experiments are easy to do, and dont make any special equipment.

We did them ourselves using roughly string, a a couple of(prenominal) large nuts, a pen, and a look, and got good results for all three tests in about 20 minutes. Herea list of what youll need for each(prenominal) group doing the experiment: - a makeup of string at lea st 1 metre long - 3 or 4 weights, all the s! ame - a pen and tape, to attach the pendulum to a shelf - a watch that counts seconds - pencil and paper to record the results Its also easier if you urinate some(prenominal) people doing the experiments, so that one person is free to time the swings. When youre ready, here are the three experiments. They are qualify up such that the answers are not apparent, but at that location are links to descriptions...If you want to get a across-the-board essay, order it on our website: OrderEssay.net
