Question

state three factors on which time period of a simple pendulum depends ​

Answer 1

☬αηѕωєя☬

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.

• The equation of time period of a pendulum is

$\pink{ \dashrightarrow{T = 2\pi \sqrt{ \dfrac{l}{g} } }}$

Since 2π is a constant , the time period mainly depends on 2 parameters :

Length of pendulum

Gravitational acceleration at that place

Concept

Length of pendulum means the distance of centre of mass of Bob from the separation distance. It doesn't just signify the real length of the string from which the Bob hangs.

Another thing is that :

Gravitational acceleration at any place depends on many factors like latitude , rotational motion of Earth , altitude of that place , etc. All these factor determine the time period of a pendulum.
