NEET Physics Damped & Forced Oscillations MCQ Question
What happens to the mechanical energy in a real oscillating system due to damping forces?
It increases due to external forces.
It remains constant throughout the motion.
It decreases and converts to thermal energy.
It becomes kinetic energy only.
Correct Answer
Detailed Explanation
The mechanical energy in a real oscillating system decreases during oscillations because external forces, such as drag, inhibit the oscillations and transfer mechanical energy to thermal energy.
