Simple pendulum

A simple pendulum is a mass (called a bob) attached to a string or rod of fixed length that swings back and forth under the influence of gravity.

The period of a pendulum is the time it takes to complete one full back-and-forth swing.

The period of a simple pendulum is affected by the length of the string and the acceleration due to gravity, but not by the mass of the bob.

The formula for the period (T) of a simple pendulum is T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Frequency is the number of complete oscillations or swings a pendulum makes in one second, measured in Hertz (Hz).

Frequency (f) can be calculated using the formula f = 1/T, where T is the period of the pendulum.

The period and frequency of a pendulum are inversely related; as the period increases, the frequency decreases and vice versa.

The unit of measurement for the period of a pendulum is the second (s).

The frequency is 0.7 Hz (42 oscillations/60 seconds).

A pendulum with a longer string will have a longer period, meaning it takes more time to complete one full swing.
