Students move past the misconception that friction inhibits our ability to do things by watching videos and participating in corresponding activities. Activities which range in difficulty include calculating the coefficient of friction.

This lesson explains the difference between static and kinetic friction. It is 1 of 2 in the series titled "Static & Kinetic Friction." [6:58]

In the following video Paul Andersen explains how contact forces result from interatomic forces. [5:29]

A video lesson investigating how frictional forces are involved in almost all of your everyday activities. Understand that the resistance you feel when sliding objects past each other or moving objects through water and air is friction....

In this video lecture, the topics of static and kinetic friction are explored with examples. The video discusses free-body diagrams and the forces that affect the movement of objects. [9:49]

This lesson provides the learner with example problems involving tension forces. It is 1 of 2 in the series titled "Practice w/ Tension Forces."

This lesson demonstrates how tension forces can be used to determine the friction force acting on an object. It is 1 of 2 in the series titled "Tension Forces & Friction."

This lesson provides the learner with example problems involving tension forces. It is 2 of 2 in the series titled "Practice w/ Tension Forces."
