Why is it easier to move a heavy object once you initially begin? Help your class explore the differences and similarities between static and kinetic friction as they view the informative video segment about motion. They learn about each...

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

This tutorial provides a mathematical interpretation of kinetic friction as compared with a normal force. [4:27]

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]

Sal Khan demonstrates how to calculate the coefficient of kinetic friction (correction made in next video). [9:08]

This lesson demonstrates how to make calculations using kinetic friction. It is 1 of 2 in the series titled "Calculating Kinetic Friction."
