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. When a car slows down, the friction between the road and the tires helps to bring the car to a stop as the wheels slow down. It is the friction between the wheels and the brake pads that causes the wheels to slow down.

The amount of force exerted (thrust) on a surface per unit area is defined as ‘Pressure’.
or
The force applied perpendicular to the surface of an object per unit area over which that force is distributed.
For example, a brick sitting on a surface exerts a force equal to its weight on the object it is resting on. Now we know that a rectangular brick has a wide surface and a thin surface on the sides. By changing the orientation of the brick resting on a surface, we are effectively changing the pressure acting on the surface by the same brick. See the image below for more information.

Area =2 mm
=0.001*2
=0.002m sq
Force applied =2N
Pressure=f/a
2/0.002
=2/2/100
=100pascal
