15.5 Damped Oscillations – General Physics Using Calculus I

A damped sine wave or damped sinusoid is a sinusoidal function whose amplitude approaches zero as time increases. It corresponds to the underdamped case of damped second-order systems, or underdamped second-order differential equations. Damped sine waves are commonly seen in science and engineering, wherever a harmonic oscillator is losing energy faster than it is … WebSep 12, 2024 · Figure 15.6. 4: The position versus time for three systems consisting of a mass and a spring in a viscous fluid. (a) If the damping is small (b < 4 m k ), the mass oscillates, slowly losing amplitude as the energy is dissipated by the non-conservative force (s). The limiting case is (b) where the damping is (b = 4 m k ). WebJun 7, 2024 · 5. The function you are fitting the data to is not a good match for the data.
