1. What is a simple harmonic oscillator? a) a system that satisfies a differential equation containing the 0th, 1st and 2nd derivatives of the displacement. b) a system exclusively acted on by a restoring force or torque that is proportional to the displacement. c) a system that follows any type of periodic motion, like that described by a triangular function. 2. What's true about the simple pendulum? a) The restoring force is the tension force. b) None of the other answers is correct. c)The simple pendulum always behaves like a simple harmonic oscillator. d) The angular frequency depends on the mass of the point mass attached to the string and the length of the string.
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.
