Detailed explanation-1: -Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards.

Detailed explanation-2: -Again, it must be static friction. The static friction force on the front wheels accelerates the car forward.

Detailed explanation-3: -Sliding friction Rolling friction takes place when an object rolls on the surface. Sliding friction takes place when two surfaces are rubbed against each other. Rolling friction takes place due to the deformation of surfaces.
