The bottom part of a fraction is the denominator.
That's where they get the friction

The two types of friction that occur when rolling a ball from the top of a hill to the bottom are kinetic friction between the ball and the surface it rolls on and air resistance as the ball moves through the air.
Adding sandpaper to the bottom of a sled to slow it down is an example of intentionally increasing friction.
Bobby Friction's birth name is Paramdeep Singh Sehdev.

Yes, rubber on the bottom of your shoes can increase friction with the ground. The rubber material provides traction and grip, helping to prevent slips and falls. However, the effectiveness of the rubber in increasing friction can depend on factors like the texture of the sole and the condition of the rubber.
The group name for push gravity and friction is contact forces.
The bottom bracket where 3 frame arms meet is supplied with ball or roller bearings which are able to reduce friction very substantially. There are ball or roller bearings also in the gear changing mechanism, in the top and bottom of the "headstock", the front tube into which the handlebar fits, in the pedals, and in the hubs of both wheels.
