Question
Proper inflation of tyres of vehicles saves fuel. Why?
Solution
When the tyres are not properly inflated, the tyres get flattened at these points the area of contact increases. Hence, the rolling friction increases due to increase in the area of contact.
When tyres are properly inflated, the area of contact decreases and, therefore, force of rolling friction decreases.
