What is critical damping?

Critical damping is a condition in which a vibrating system returns to its equilibrium position as quickly as possible without oscillating. It occurs when the damping force is just enough to prevent any overshoot or oscillation, resulting in a smooth and rapid return to the rest position.

Split SHM numerical x= 10 sin

This question involves splitting a simple harmonic motion (SHM) represented by the equation x = 10 sin(ωt + φ) into two separate harmonic motions. The goal is to express the original motion as a combination of two simpler motions with different amplitudes and phases.
