What is terminal velocity? What are the factors on which terminal velocity depends?

Solution:

The terminal velocity of an object is the maximum constant velocity acquired by the object while falling freely in a viscous medium.
Terminal velocity (v) of an object of radius (r) density () moving through a viscous medius of viscosity  and density  is given by

Hence, terminal velocity depends on

  1. radius of the object
  2. coefficient of viscosity of the medium
  3. density of the object.
  4. density of the medium
