Lots of friction is needed in car brakes to slow down or stop the vehicle effectively, in shoe soles to provide traction and prevent slipping, and in rock climbing equipment to secure climbers on the rock surface.
The braking system on a car depends on lots of friction between the brake pads and the brake disk.
Rubber has lots of friction because it has a high coefficient of friction, meaning that it can grip surfaces effectively. The uneven surface of rubber molecules creates more contact points with other surfaces, resulting in greater friction. Additionally, rubber is elastic and can deform slightly to conform to the surface it is in contact with, increasing the contact area and therefore the friction.
Objects with smooth surfaces or lubrication between them tend to have less friction. In a vacuum or in microgravity environments, there is also less friction between objects.

Ice has little friction. Sandpaper has lots of friction.
it can create lots of heat
When you read a Horror Novel lots of friction on it

You want less friction. Then you will go faster.
In the bearings, where you want as little friction as possible.

Because a round object has less surface area in contact with the solid surface it's being propelled upon, there is less friction between the two objects and the sphere will travel farther on that surface than a flat object (lots of contact....lots of friction....and therefore, resistance to motion) due to the difference in friction.
