Question

what is a simple pendulum? what are the factors affecting the time-period of a pendulum?

Answer 1

simple pendulum is the bob connected to a thread which is attached in stand through rubber cork
laws of length
laws of amplitude
law of frequency
law of time period
etc

Answer 2

A simple pendulum is a weight suspended from a pivot so that it can swing freely.When it is displaced sideways from.resting,equilibrium position,it is subjected to restoring force of gravity
Factors affecting time period of simple pendulum are:-
length of pendulum
angle of amplitude
gravitional field strength
mass of Bob


hope this will help u
