A 1 kg sphere is tied onto the bottom of a 3 m wire hanging vertically. The sphere is then pushed so that it reaches an angle of 30 (degrees) with the vertical before turning back around. What is the period for this motion? The sphere is then stopped and pushed again from the bottom so that it reaches an angle of 40 (degrees) with the vertical line. Does this have a longer or shorter period of oscillation than before?
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.
