Draw a neat diagram of a simple pendulum. Show on it the effective length of the pendulum and its one oscillation.

State how does the time period of a simple pendulum depend on —

(a) length of pendulum,

(b) mass of bob,

(c) amplitude of oscillation and

(d) acceleration due to gravity.

Name two factors on which the time period of a simple pendulum depends. Write the relation for the time period in terms of the above named factors.

How do you measure the time period of a given pendulum? Why do you note the time for more than one oscillation ?
