Rolling resistance is a force that opposes the motion of a rolling object, such as a wheel or tire, as it moves over a surface. This resistance is primarily caused by the deformation of the materials involved (like the tire and the ground) and the energy lost in the process. When a tire rolls, it undergoes a slight deformation at the point of contact with the ground, and as it rotates, it recovers its shape.
