The Normal force, solving Inclined problems an introduction

This quick video explains what the normal force is and how it changes with inclined planes. I go through how to solve an inclined plane problem, incorporating the normal force

Absolutely excellent explanation, thank you so much.

Thank you so much. I understand all of the class material but whenever it comes time to decide which is sine and which is cosine on inclined plane problems I always second guess myself. This is a great explanation!

This was really helpful...thank you very much

[kageyama-kun]

cos ○ = adjacent side/hypotenuse
cos○=weight/F_N
F_N=cos○/weight

How come its F_N=Weight×cos○?

Please clarify and correct me

At 4:50 you state that "cos(x)" is less than (1); yet, at the "0" degree angle cos(x) does equal (1). Nevertheless, great video!
