What this topic covers
Illustration, explanation, and definition of S.H.M. using a loaded test-tube, simple pendulum, spiral spring, and bifilar suspension. Speed and acceleration of S.H.M., relating linear and angular speeds/accelerations. Period, frequency, and amplitude of a body executing S.H.M. Experimental determination of 'g' with simple pendulum and helical spring (theory but not formula derivation). Energy of S.H.M. with simple problems. Forced vibration and resonance. Distinction between inertia mass and weight.
