The Simple Pendulum | Physics
Using this equation, we can find the period of a pendulum for amplitudes less than about 15º. For the simple pendulum: T =2π√m k = 2π√ m mg L T = 2 π m k = 2 π m m g L. Thus, T =2π√L g T = 2 π L g for the period of a simple pendulum. This result is interesting because of its simplicity.

Multiply the result from Step 1 by the earth's gravitational acceleration, which is 9.81 meters per second squared: 0.342 x 9.81 m/s^2 = 3.36 m/s^2. Multiply the result from Step 2 by the bob's mass. For example, if the bob weighs 2 kilograms (kg), the calculation is 3.36 m/s^2 x 2 kg = 6.72. This is the force pushing the pendulum bob, measured ...

L is the length of the pendulum (of the string from which the mass is suspended); and. g is the acceleration of gravity. On Earth, this value is equal to 9.80665 m/s² — this is the default value in the simple pendulum calculator. You can find the frequency of the pendulum as the reciprocal of the period: f = 1/T = 1/[2π√(g/L)]

History of the Pendulum | Sciencing
History of the Pendulum. A pendulum is an object or weight suspended from a pivot point. When a pendulum is set in motion, gravity causes a restoring force that will accelerate it toward the center point, resulting in a back and forth swinging motion. The word "pendulum" is new Latin, derived from the Latin "pendulus," which means "hanging."
