Question

Which force is acting here?

  1. Static friction
  2. Sliding friction
  3. Rolling friction
  4. Fluid friction

hintHint:

Fluid friction is a force that restricts the movement either within itself or of another medium moving through the liquid (including air).

The correct answer is: Fluid friction


    When a man with a parachute flies in the air, it causes fluid friction.
    • The frictional force formed in air or liquid is the liquid/fluid frictional force.
    • It resists the motion caused by the contact of an object with air.
    • For example: Liquid frictional force is caused when a man with a parachute flies in the air.
