Answer #1

mass on a spring, rotating circular motion and pendulum corresponds to SImple Harmonic Motion.

Simple pendulums behave much like harmonic oscillators like springs. The period of a pendulum is determined by its length and not its mass. In the case of a pendulum, the restoring force is provided not by a spring but by gravity,

                            F= -kx

If we consider a point on the rim of a disk as it rotates anticlockwise at a constant rate around a horizontal axis, it produces a sinusoidal graph. Plot the position of a mass on a spring bouncing up and down in simple harmonic motion as a function of time which is a sinusoidal graph too.

A torsional pendulum executes simple harmonic motion by rotating about its axis. It consists of a coil spring attached to a balance wheel (a disk in this case). Recall that a torsional pendulum is similar to a normal pendulum with force replaced by torque, linear displacement replaced by angle turned, and mass replaced by moment of inertia. The spring constant is replaced by torsion constant. Assume the balance wheel of such a torsional pendulum is doubled in size but the...

Let’s think back to the lab for simple harmonic motion. Consider the setup for the simple pendulum. The length of the pendulum is 0.60 m and the bob has inertia 0.50 kg (assume mass of the string is negligible, and small angular displacements). You conduct two experiments (A and B) to investigate the physics of simple harmonic motion. For experiment A, you pull the pendulum 5 ◦ , or π 36 radians. In experiment B, the angular displacement is 10◦...
