/sci/ what is your advice to overcome your intuitions when you began in physics? I just got out of my first physics test as a freshman and one of the problems was really fucking with my head.

First test, your first physics course?

what exactly was fucking with your mind?

imo classical mechanics is pretty aligned with intuition.

Come on dude don't act like mechanics was fucking easy... they made these questions difficult. The question was regarding a mass on a hemisphere. I'll draw it out for you.

There is also static friction acting on it. I can't even remember what we had to do with it initially but I remember the second part asking us to find and express the normal force and the last part was to find a relation between theta and r when the mass slips off.

Do you master trigonometrics?
If so, you don't have to ask yourself why are those circular formulas like that.

Literally what in this problem goes against your intuition?

Well the first problem is the FBD. Imma draw it and you tell me if it's right or not.

No, is this completely wrong? I'm trying to understand this.
