Question

9.2 Explain the factors on which friction in fluids depends.
​

Answer 1

Answer:

Explanation:

The speed of the object moving through a fluid affects the amount of friction acting against the motion of the object. More the speed, more is the friction. ... Thus, a streamlined body structure helps to cut through the fluid and reduce friction. Also, the nature of the fluid affects friction.

Answer 2

Answer:

Factors affecting fluid friction -

Frictional force on an object in a fluid depends on its speed with respect to fluid and on the shape of the object and nature of the fluid. ... All vehicles are designed to have shapes which reduce fluid friction.

for example shape of aeroplane is spindle.
