Question

Define amplitude and freqency of the pendulul. write their S.I. units.​

Answer 1

Answer:

Every vibration or oscillation has three characteristics : Amplitude ,time period and frequency. Amplitude of vibration. The maximum distance to which the bob of a vibrating pendulum goes from its central position is called amplitude of vibration or amplitude of oscillation.

si unit of frequency is

hertz (Hz)

The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.

si unit of amplitude is

metre

The SI unit of amplitude is the metre (m). The amplitude of a wave is the maximum disturbance or displacement of the medium from the equilibrium (rest) position.

hope it helps you

Answer 2

Answer:

The frequency of a pendulum is how many back-and-forth swings there are in a second, measured in hertz.
