Weight and Friction

Part of my lecture series on Fundamental Physics. You can view the full course here:
   • Physics Fundamentals (In Progress)  

Learning objectives for this lesson:
Calculate the force of gravity (weight) and normal force acting on an object resting on a horizontal surface
Understand the coefficient of static friction and coefficient of kinetic friction
Calculate the applied force necessary to overcome static or kinetic friction

In this video, I used the PhET Forces and Motion simulation as a virtual demonstration. This interactive simulation is available for free at https://phet.colorado.edu/en/simulati...
