Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.

1.Calculate the period T, in seconds (s), for the following cyclical events:
a. five classes every 375 minutes
b. ten swings of a pendulum in 6.7 s
2.Calculate the frequency f, in hertz (Hz), for the following cyclical events:
a. 120 oscillations in 2.0 s
b. 45 revolutions of a turntable in one minute
3.As a train pulls out of the station going 50 m/s it blasts its horn, what is the frequency heard by the train if the passengers still at the station are hearing 384 Hz
1) a) we have ,
Five classes every 375 minutes ( 375×60=22500 seconds)
Time period(T)= total time / no. of classes
T= (22500/5) seconds
T= 4500 seconds
Time period is 4500 seconds .
