Explanation:
Detailed explanation-1: -Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest.
Detailed explanation-2: -The soles of shoes are worn out due to the effect of friction . The soles of shoes increase the friction between surfaces because it makes the surface of the shoes rough . Thus, this is due to the fact that friction causes wear and tear of objects and reduces the life of the object .
Detailed explanation-3: -Because there is no relative motion between the shoe and the ground, the friction force is static friction.
Detailed explanation-4: -Rolling friction is the frictional force that occurs when one object rolls on another, like a car’s wheels on the ground.
