Damped Oscillation
Damping causes amplitude to:
Select the correct option:
Solution
Decrease over time
In real scenarios, oscillating systems lose energy to the surrounding environment (due to friction, air resistance, etc.). This energy loss causes the amplitude of oscillation to decrease continuously with time. The damping force is usually proportional to velocity (Fdamp=−bv), leading to an exponential decay of the amplitude: A(t)=A0e−(b/2m)t.
