The physical parameters in a simple pendulum experiment are a small-diameter bob and a string that has negligible mass, according to OpenStax College. The string should not be elastic, however. More » Science Physics Motion & Mechanics

Technically, a pendulum can be created with an object of any weight or shape attached to the end of a rod or string. However, a spherical object is preferred because it can be most easily assumed that the center of mass ... More » Math Geometry Shapes

A plumb bob is a pendulum commonly used by construction workers and surveyors to accurately locate the levels over a specific spot on the Earth?s surface. Inertial guidance systems on some aircraft instrumentation, missi... More » Science Physics Motion & Mechanics

To build a ballistic pendulum, use a cardboard box, weights, four eye hooks, nylon string, a piece of plywood and a sheet of white paper. Mount the ballistic pendulum after it is constructed. More » Science Physics Motion & Mechanics

A conical pendulum is a weight fixed on the end of a string or rod suspended from a pivot so that it can swing freely. A conical pendulum construction is similar to an ordinary pendulum; instead of swinging backward and ... More » Science Physics Motion & Mechanics

For larger amplitudes, the amplitude does affect the period of the pendulum, with a larger amplitude leading to a larger period. However, for small amplitudes (typically around a few degrees), the amplitude has no effect... More » Science Physics Motion & Mechanics
