Damped oscillation – Rankers Physics

Energy in SHM: Practice Problem & Solution

Assertion (A): In damped oscillation both amplitude and frequency change with time. Reason (R): Both amplitude and frequency vary exponentially.
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Energy in SHM. Understanding the underlying formula is key to arriving at the correct answer below:

In a damped oscillation, the amplitude decreases exponentially with time, but the frequency of oscillation (for underdamped case) remains constant. Therefore, both Assertion (A) and Reason (R) are false.
