Question

Choose the correct statement about drag in fluids.

• A. It doesn't depend on the shape of the object.
• B. It exists in solids, liquids and gases.
• C. Different objects may experience different drag in fluids.
• D. It exists only in liquids.

Answer 1

The correct option is C Different objects may experience different drag in fluids.

The force of friction exerted by fluids (gases and liquids) is known as drag.
Fluid friction depends on the shape of the object. Streamlined objects like fish experience less drag as compared to non-streamlined objects like humans.
