Question

Define pendulum .On what factor does the period of a pendulum depend and how are. they related?

Answer 1

The time period of a simple pendulum is given by



So, time period of simple pendulum depends upon the length of the pendulum, acceleration due to gravity and the temperature (as length depends on temperature). It is directly proportional to the square root of length and inversely proportional to the square root of acceleration due to gravity.

Answer 2

A Pendulum is a heavy point mass (known as Bob) suspended from a rigid support by a mass less and in extensible string

Factors on which pendulum depends are
1. Oscillation = One complete to and fro motion of the Bob of pendulum is called one oscillation
2. Time period = time taken to complete one oscillation
3. Frequency of oscillation = it is the number of oscillation made in one second
4. Amplitude
5. Effective length of pendulum
