A simple pendulum is a mass, or bob, suspended from a pivot point, such as a nail or a string, so that it is able to swing freely. When given an initial push, the mass swings back and forth in an arc, repeating the same motion over and over. A simple pendulum is used to study the effects of gravity and friction.
Relation between frequency and period of a simple pendulum:
The relation between frequency and period of a simple pendulum is given by the equation:
T = 1 / f
Where,
T = period of a simple pendulum (in seconds)
Relation between frequency and length
The frequency of a simple pendulum is inversely proportional to the length of the pendulum. This means that as the length of the pendulum increases, the frequency of the pendulum will decrease. This is because the longer the pendulum, the more time it takes to complete one oscillation, thus reducing the frequency.
