Question : Which of the following statements is correct?
I. Rolling friction is greater than the sliding friction.
II. The frictional force exerted by fluids is called drag.
Option 1: Only I is correct.
Option 2: Neither I nor II is correct.
Option 3: Both I and II are correct.
Option 4: Only II is correct.
Correct Answer: Only II is correct.
Solution : The correct option is Only II is correct .
Rolling friction is generally less than sliding friction. The frictional force exerted by fluids, such as air or water, is called drag. It opposes the motion of an object through the fluid, affecting its speed and direction. Drag force increases with the object's Velocity.
