1. Consider two systems experiencing simple harmonic motion: a mass-spring system and a pendulum. Which of these systems would experience a change in frequency if the mass in the system were changed? O The pendulum O Both O Neither O The mass-spring system 2. A pendulum is hung from the ceiling of an elevator. When the elevator accelerates upwards, the period T of the pendulum is --- ✓the period when at rest. 3. A 2.70kg mass is hung from the ceiling by a string of length 1.60m and mass 0.00300kg. The string is plucked and a transverse wave travels through it. What is the speed of the transverse wave? m
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.
