Background A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. Tip: If the meter stick does not seem to stably sit on the backs of the chairs, you can try to tape the ends of the meter stick to the chairs. Procedure, Pull the strings tight (by holding on to the washers or pennies at the ends) and position the strings at the same angle from the meter stick. Have an assistant ready with a stopwatch. Drop the longer pendulum and, at the same time, have the assistant start the stopwatch.
Electricity (Science With Simple Things Ser No 32. It is, in short, a classically simple TOPS learning system.
Electricity (Science With Simple Things Ser No 32). Ron Marson. Armed with a stopwatch and calculator, your students will graph length vs frequency into a beautiful curve they ll stand this curve on its head by plotting the period, then straighten it back out by squaring the period. This straight line leads directly to a simple pendulum equation with powerful applications. Reinforce all this great learning with other simple things that oscillate, from bouncing springs to chains of paper clips.

Stripped down to its most basic form, a pendulum is nothing more than a weight that has been suspended from a pivot, and is capable of swinging freely from side to side when given an initial push, keeping a constant amplitude.

A simple pendulum has a small-diameter bob and a string that has a very small mass but is strong enough not to stretch appreciably. The linear displacement from equilibrium is, the length of the arc. Also shown are the forces on the bob, which result in a net force of toward the equilibrium position-that is, a restoring force. Pendulums are in common usage. Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It’s easy to measure the period using the photogate timer. You can vary friction and the strength of gravity.
The chaotic pendulum is used in my classroom in our discussions of resonance, harmonic motion, and chaotic motion. With small amounts of energy, it's movement is predictable, but more energy is added the movement of the arms become unpredictable. I am currently in my 38th year of teaching.

This Day in History: Sep Foucault pendulum inventor, Léon Foucault, is born. Foucault's pendulum demonstrates the rotation of the earth.
This cool physics demo illustrates the simple harmonic motion of a pendulum while teaching kids the important concepts of potential and kinetic energy. The movement of a pendulum is called simple harmonic motion: when moved from a starting position, the pendulum feels a restoring force proportional to how far it’s been moved. Put another way, it always wants go back to where it started. Pendulums move by constantly changing energy from one form to another
