NEET Physics: Physics - Oscillations questions with solutions

Q1. In reality, a spring won't oscillate for ever. will \( \quad \) the amplitude of oscillation until eventually the system is at rest.

1. Frictional force, increase
2. Viscous force, decrease
3. Frictional force, decrease
4. Viscous force, increase

Answer: Viscous force, increase

A viscous force is a damping force that opposes motion and removes mechanical energy from the system. Because of this energy loss, the oscillation amplitude decreases over time until the spring comes to rest.
