Question

IV. Define the following:

(i)Time period of a pendulum
(ii)Frequency of a pendulum
(iii)Average speed​

Answer 1

Answer:

i)The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing.

ii)The frequency of a pendulum is how many back-and-forth swings there are in a second, measured in hertz. f = [√(4.9)]/6.28 = 2.21/6.28 = 0.353 Hz.

iii)Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip.

Answer 2

Answer:

i)Time period of a pendulum--- It is the time taken to complete one oscillation.It is donated by T . It unit is second(s)

ii) Frequency of a pendulum- It is the number of oscillation made in one second. It is donated by f or n.

iii)Average speed--The average speed of a body is the total distance travelled by the total time taken to cover this distance.
