Question

What is a simple harmonic motion? What are the relevant quantities that should be considered

in simple harmonic motion? Identify and explain these quantities

Answer 1

Simple harmonic motion is any kind of periodic motion that can be described by trigonometrical functions and where the restoring force follows the following criteria:

1) It is directed toward the displacement of the object;

2) It is directly proportional to the magnitude of the displacement.

Simple harmonic motion can be described by the position $x(t)$ of the object at any moment of time $t$, the amplitude $A$ of oscillations, the frequency $f$.
