What a legend. I am from the UK and am so glad I found your videos. Keep up the superb

Thanks for the video! I'll never **tire** myself out on a similar problem again.

Thank you for helping me!!! I feel like I can understand ap physics now!

Hello. Thank you so much for the video. I was wondering if you could have done it this way. Fc = Fg - Fn cos(30) = ma. I got 4.44 N for the normal force.

Thank you so much!

You deserve more subscribers. Keep up the good work 👍

Thank you so much for all the videos you've uploaded; they've saved me in AP Physics this year! On a sidenote, do you know when you will have videos on AP Physics C E&M? If so, do you think that they may be out before the upcoming exam in May 2018?

Once again, thank you for all the effort you have put into this channel.

Hey Mr.P, quick question, is there no force of kinetic friction because the tangential velocity is instantaneous? Was just a little bit confused as to why there was no friction.

[geraldtan]

hi thanks for the video but may I ask why does the instantaneous tangential velocity of the cars decrease as the car goes uphill?

[anniechen]

your videos are so useful!!! thank you so much :)

Should not we calculate cosinus for angle 90-32? I don't get it...

Why is force of gravity being added by centripetal force. Shouldn't it be subtracted or is this one of those situations where you have to use centrifugal force?

[eaglekraft]

I understand the math reason as to why the magnitude of the force of normal decreases as the car goes up the hill. But how can I make sense of that?

Thank you very very very very much💐💐💐💐💐💐💐💐

If there are agents for force and the force of gravity can't be seen, is the force of gravity a secret agent?
