Answer 2

Both the statements are correct.

* Friction is the resistive force that comes into play when one body is in motion with respect to another.

* It tries to resist the motion and thereby aids in activities like running, walking, etc.

* Rolling friction is less than sliding friction as the surface area in contact between the two given surfaces in case of rolling friction is lesser as compared to that of sliding friction.

* This leads to a greater force of contact and thereby more friction in case of sliding friction.
