CBSE · Class 11 · Physics · OscillationsWhich of the following conditions is essential for a motion to be Simple Harmonic Motion (SHM)?
Step-by-Step Solution
In Simple Harmonic Motion (SHM), the restoring force or acceleration is directly proportional to the displacement from the mean position and acts in the opposite direction to the displacement ($a = -\omega^2 x$).
Detailed Options Breakdown
Option : Acceleration is constant
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Oscillations.
Option 1: Acceleration is directly proportional to displacement and opposite to it (Correct Answer)
Correct choice. Refer to the step-by-step verified solution guidelines above for details.
Option 2: Velocity is directly proportional to displacement
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Oscillations.
Option 3: Restoring force is independent of displacement
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Oscillations.
