نوساني حرکتونه او رپېدونکی

From the swing of a clock pendulum to the vibration of atoms in a crystal, oscillations are one of the most common patterns in physics. This short university-level course derives simple harmonic motion from Newton's second law and connects it to experiments you can do with a string and a stone.

Prerequisites: Newton's laws and basic calculus (derivatives of $\sin$ and $\cos$).
