Question

Explain the friction exerted by fluids? (40 to 50 words) in points with examples

Answer 1

Dear student,

Air is very light and thin. Yet it exerts
frictional force on objects moving
through it. Similarly, water and other
liquids exert force of friction when
objects move through them. In science,
the common name of gases and liquids
is fluids. So we can say that fluids exert
force of friction on objects in motion
through them.
The frictional force exerted by fluids is
also called drag.



Examples of Fluid Friction

If there is a wet surface between two thin glass plates, you will notice that platest get stucked and the bottom plate doesn’t fall when you hold only the top one.

When any object is dropped in a fluid, the extent of splash is depended on the fluid friction of that particular fluid.

You find lighter dust particles move fast on the surface of a flowing river. This is due to the high velocity gradient at the top layer of water due to lower dynamic fluid friction at that layer.

Hope you got the idea
