A pendulum is a simple device composed of a weight suspended on a string, wire, metal or other material that swings back and forth. Pendulums have been used in grandfather clocks and the like to keep time. Scientific principles govern what affects the swing rate of the pendulum.
Investigate the motion of a simple pendulum and determine how the motion of the pendulum is related to its length. A pendulum is an object, hung from a fixed point, that swings freely back and forth under the action of gravity. A playground swing Figure 1 is an example of a pendulum.
Pendulums are often used as tools for spiritual healing and inner growth. Defined as objects attached at the end of a string or metal chain, when suspended from a stationary position, a pendulum will swing back and forth or in a circular motion. The typical image of a pendulum is that of an object with four metal balls, such as that on an employee's desk, also known as Newton's pendulum.

Introduction Did you know that playground swings can provide a good lesson in physics—as well as lots of fun? The back-and-forth motion of a swing is an example of a pendulum. We see pendulums in other areas of our lives as well, such as in grandfather also known as longcase clocks. But pendulums can do more than provide fun at recess and help tell the time—among other scientific applications, they can show that the earth is huge!
The swinging Atwood's machine SAM is a mechanism that resembles a simple Atwood's machine except that one of the masses is allowed to swing in a two-dimensional plane, producing a dynamical system that is chaotic for some system parameters and initial conditions. The conventional Atwood's machine allows only "runaway" solutions i. The swinging Atwood's machine is a system with two degrees of freedom.
