"" damped force equation ""​

Explanation:

Many systems are underdamped, and oscillate while the amplitude decreases exponentially, such as the mass oscillating on a spring. The damping may be quite small, but eventually the mass comes to rest. If the damping constant is b=√4mk, the system is said to be critically damped, as in curve (b).
