A simple harmonic oscillator is constructed by attaching a block of mass to a horizontal spring on a frictionless tabletop. A siren is attached to the block. While you are observing the frequency of the siren, you notice it shift, going from being higher than the source frequency and increasing to being higher than the source frequency but decreasing. Which of the following happened? Explain your answer in detail. A) The block crossed the equilibrium position while moving away from you. B) The block crossed the equilibrium position while moving towards you. C) The block arrived at the maximum displacement that is closest to you. D) The block arrived at the maximum displacement that is farthest away from you. E) None of the above
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.
