Static and Kinetic Friction - Forces in MCAT Physics

This video defines the forces of static and kinetic friction using real-life examples and logical explanations.
You’ll learn how to draw free body diagrams that incorporate friction in the horizontal plane to oppose an applied force, for both objects in motion and objects that are stationary on a flat surface.
You’ll also learn about the coefficient of static and kinetic friction, what it means for an object’s resistance to either move or slow down and how it fits into the equation for friction.
Finally, you’ll see me walk through a full-length practice problem that includes kinematic equations and several tips and tricks for solving similar problems using MCAT Math.

I was JUST doing a static friction problem on UWorld and came to YT to watch some more videos, and you just uploaded this 1hr ago?? Queen!!

thank you so much. So clear and fun to watch - I really appreciate it

Your videos are a blessing. I am so grateful to you for your teaching passion and generosity. Thank you.

lolz You lost me around 13:00 when deriving from other equations happened xD but I love the video super helpful

At 4:43 the force F, what force is that? And for how long time does it work?
