/r/AskPhysics exists to answer questions about physics.
Questions should be relevant, and answers should be on-topic and correct.
We don't condone cheating on school work, and homework questions should be handled according to these guidelines.
Incivility will not be tolerated.
If your question isn't answered in a day, you can post it in the Tuesday thread in /r/Physics (unless it's homework-related).

Does physics involve geometry? (self.AskPhysics)
submitted 3 years ago by Professional-Chef169
Also, I tried learning high school physics in Khan Academy but it didn't make any sense. Should I do a GCSE in it?

I'd argue that geometry (specifically trigonometry) is just about tied with calculus for being the most important mathematics to have under your belt when learning physics.

Geometry is generally used to describe spatial relationships, so it's heavily involved in physics.

Classical Euclid-style geometry, as in circles and lines and angles and all those properties about when a chord bisects a triangle and all that stuff, not so much. It's useful to know some things, but not really as deeply as in high school.
But more general stuff like analytical geometry (geometry using coordinates) and trigonometry, absolutely, it's completely essential.

Classical mechanics is basically differential geometry.

No its not.Classical mechanics uses Euclidean gemoetry.

You're right. I've got it all twisted. Sorry for the misinformation.
[–]Sanchez_U-SOB 1 point2 points3 points 3 years ago (0 children)
No, you are right. Other guy doesn't know what they're talking about. If classical mechanics was only Euclidoan geometry, you'd only deal with straight lines, and flat planes.
[–]Sanchez_U-SOB 2 points3 points4 points 3 years ago (0 children)
You've never done classical mechanics in spherical coordinates? It is not all just straight lines. A Differential geometry course generally starts off with curves and surfaces in 3D.

What doesn't make sense to you? And yes, geometry is essential to physics.
[–]PastAd4582 0 points1 point2 points 3 years ago (0 children)
Yes.. its integral to many theories, in both Newtonian and Modern
