Question

what is rolling friction?❤✌​

Answer 1

Answer:

$\huge{\mathbb{ANSWER : -}}$

Rolling friction is the friction between two surfaces when one or both are free to rotate rather than slide at the point of contact. It is caused by the fact that no surface is perfectly smooth and round and no material is perfectly elastic.

Answer 2

$\huge\sf{\underline{\underline{\red{Answer-}}}}$

• Rolling friction can be defined as a friction in which the body rolls on a surface.

• The force that resist the motion of a rolling object on a surface is known as rolling friction.

• This Force is recovered when the applied pressure is decreased or removed.

• Rolling of wheel, cylinder and other objects in a circular direction is a good example of rolling friction. It is much smaller than sliding friction.

• Rolling friction also known as rolling resistance and often called rolling drag.
