Question

Liquid and gases also exert friction on object moving through them.

• A. True
• B. False

Answer 1

The correct option is A True

1. A force that resists the movement of a body moving through either a liquid or a gaseous medium is known as fluid friction.
2. When a swimmer swims or a boat moves through the liquid, frictional or drag force opposes the movement.
3. Similarly, when an object falls or flies through the atmosphere, air opposes its motion. Sometimes, an object falling down through the atmosphere, like a meteor or a satellite, may get burnt owing to the excess heating effect due to this fluid friction.

Hence, the given statement is True.
