What is ratio of force of resistance due to liquid to that due to gravity? For any object for example a ball falling in a liquid with constant velocity, what will be the ratio?

  • $\begingroup$ I'm curious about how gravity is resisting (the motion) in this case. Isn't gravity always attractive? $\endgroup$ – 299792458 Jan 17 '16 at 6:50
  • $\begingroup$ @TheDarkSide the resitance is due to the drag force. $\endgroup$ – Alex Prior Jan 17 '16 at 7:40
  • $\begingroup$ You might to take a look at the Galilei number, it's a non-dimensional parameter that describes the ratio between gravitational and viscous forces. $\endgroup$ – Darwin Jan 17 '16 at 19:28

If the velocity is constant then ratio is 1:1
