what is viscous force?

Viscous force is the internal resistance force offered by a fluid when it is being acted upon by a force tangential to its surface.

Viscosity or viscous force is the force between a body and any fluid moving along it in a direction so as to oppose the motion of the fluid along with the object.

Viscous Force

  • When a solid moves in a fluid, it will experience resistance to its motion
  • Viscosity Depends on the speed of the object.
  • Viscosity Depends on the fluid involved
  • In denser fluids Higher viscosity is present
  • Viscosity Dependant on nature of a fluid
  • Viscous forces in a fluid are proportional to the rate at which the fluid velocity is changing in space.
