alleryWhat is damping?
AEnergy dissipating so amplitude falls
BEnergy building so amplitude rises
CThe wave changing to a new medium
DThe frequency doubling over time
Answer & Solution
Correct answer: A. Energy dissipating so amplitude falls
1. A driving force puts energy into an oscillating system.
2. Over time that energy dissipates and the amplitude gradually reduces to zero.
3. That gradual loss is what is called damping.
4. Without any damping or driving force, the system would keep its natural frequency.
