Question

The force of friction always opposes motion or the tendency of motion

• A. True
• B. False

Answer 1

The correct option is B False

The given statement is false.

Friction does not always opposes motion. For eg when a car is accelerating forward , the tyres push against the road in backward direction. Friction pushes itself in forward and car also pushes forward. Thus friction and motion are in same direction.

Similarly when a runner accelerates forward the shoe pushes backward, friction pushes forward and runner pushes forward. Thus both are in same direction

Hence force of friction does not always opposes motion or the tendency of motion.
