Examples :
Rubbing both hands together to create heat.
A sled sliding across snow or ice.
Skis sliding against snow.
A person sliding down a slide is an example of sliding friction.
A coaster sliding against a table.
A washing machine pushed along a floor.
An iron being pushed across material.
There are several ways to reduce friction:
The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example.
Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.
