Physics-Damped & Forced Oscillations
NEET Physics Damped & Forced Oscillations MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Which of the following statements about damped and forced oscillations is correct?
A
Damped oscillations result in a continuous decrease of mechanical energy due to external forces.
B
The displacement of a damped oscillator remains constant over time.
C
The damping force is always equal to the restoring force in a damped oscillator.
D
Forced oscillations occur when the system oscillates at its natural frequency only.
Correct Answer
Option A
Detailed Explanation
Damped oscillations are characterized by a decrease in mechanical energy due to external forces that convert energy to thermal energy, as stated in the NCERT context. Other options incorrectly describe the behavior of damped and forced oscillators.
