Question

Define the following in connection with a simple pendulum.
(a) Time period
(b) Oscillation
(c) Amplitude
(d) Effective length.

✓

Answer

(a) Time period ( T ) : "is the time taken to complete one oscillation." Its unit is second
(s) and time period is denoted by ' $T$ '
(b) Oscillation : "One complete to and fro motion of the pendulum" is called an oscillation.
i.e., motion of bob from B to C and then C to B is one oscillation.

(c) Amplitude : The maximum displacement of bob from mean position on either side is called amplitude
Amplitude $= AB$ or AC . It is denoted by ' a '.
(d) Effective length: The length between the point of suspension and centre of gravity of bob of a pendulum is called effective length.
