Question

Undamped oscillations are practically impossible because

• A. there is always loss of energy.
• B. there is no force opposing friction.
• C. energy is not conserved in such oscillations.
• D. None of these.

Answer 1

The correct option is A there is always loss of energy.

Underdamped oscillation is practical because there always be resistive force present in reality which will try to make an oscillating body to lose its energy. This loss of energy makes the motion damped motion.
