Question

In which of the following situation is friction an advantage ?

• A. wear and tear of machines
• B. wear and tear of foot wares
• C. helps us to hold objects
• D. wear and tear of a tyre

Answer 1

Answer:

C. helps us to hold objects

• Friction is an advantage when it helps us to hold objects securely. Without friction, objects would slip from our hands easily. The other options—wear and tear of machines, footwear, and tires—are examples where friction causes disadvantageous wear and damage, not benefits.
