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.

Very helpful❤

[@avocadosnumber498]

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!

You're very welcome!

This was really helpful...thank you very much

[@letsstudyeverything343]

Great.

cos ○ = adjacent side/hypotenuse cos○=weight/F_N F_N=cos○/weight How come its F_N=Weight×cos○? Please clarify and correct me

[@vedanthbharadwaj3960]

For problems on inclines you talk about the weight because you need the acceleration along the ramp and the component of the weight pushing the cart into the surface of the ramp so it basically makes sense to resolve weight into its components. But if you talk about something like a car moving in rotational motion you need to talk about the acceleration (if it's going on a curved bank: if you don't understand what that is go check up NASCAR races and see how the road changes angle) so you resolve it in terms of normal force to get: Fncostheta=mg. This should help you in other questions. But for your question mainly, the one Fn=mgcostheta is right

[@vedanthbharadwaj3960]

If you want to know why, then please watch Matt Anderson's video on inclined planes. I would prefer not to give the explanation here, because it's quite lengthy. Watch the video, if you have any doubts you can ask 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!
