Question

Fluid friction depends on ______

• A. speed of the object
• B. shape of the object
• C. nature of fluid
• D. all of the above

Answer 1

The correct option is D all of the above

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. If the object is broad, it gives more area for the friction to act on. Thus, a streamlined body structure helps to cut through the fluid and reduce friction. Also, the nature of the fluid affects friction.
