Question

why rate of damping is in exponential decay form​

Answer 1

Answer:

Underdamped oscillations within an exponential decay envelope. ... Larger amounts of damping (see overdamping) cause the solution to more slowly approach zero as it moves slowly through the damping fluid, whereas smaller amounts of damping cause the solution to oscillate more rapidly around zero.

Answer 2

Answer:

Underdamped oscillations within an exponential decay envelope. ... Larger amounts of damping (see overdamping) cause the solution to more slowly approach zero as it moves slowly through the damping fluid, whereas smaller amounts of damping cause the solution to oscillate more rapidly around zero.
