The term sliding friction refers to the resistance created by two objects sliding against each other. This can also be called kinetic friction. Sliding friction is intended to stop an object from moving.
The amount of sliding friction created by objects is expressed as a coefficient which takes into consideration the various factors that can affect the level of friction. These various factors that can impact sliding friction include the following:
Specific examples of sliding friction include:
As these examples show, there are many different situations where sliding friction exists and where sliding friction creates resistance as objects rub against each other. This type of friction is different than rolling friction where one item can roll and the friction typically slows the rate of movement.
There is a good chance you have encountered sliding friction examples in the real world. Now you will be able to recognize these examples when you come upon them since you have a better understanding of what sliding friction means.
