Question

Damping force on a spring mass system is proportional to which of the following quantities?

(a) Velocity

(b) Acceleration

(c) Displacement from mean position

(d) (velocity)^2

Answer 1

Right choice is (a) Velocity

The explanation is: We know from Stoke’s law that damping force is proportional to velocity of a body. It also depends on the surface area in contact with the source of particles causing damping, like air.
