If I wanted to study physics...

What are the basic things I should know (besides algebra, calculus, etc)?For some reason I never studied physics very much. The only thing I know is Newton's three laws of motion. :?If I wanted to study physics...
I think algebra, geometry, trig, and calc would be enough. If I wanted to study physics...
Physics is the ****
Mechanical? You need to know math up through calc I at least.
[QUOTE=''FragStains'']I think algebra, geometry, trig, and calc would be enough. [/QUOTE]Yeah. I'm doing Physics A-Level right now and that's the only maths I need. So far, at least.
It would be useful if you're confident in representing numbers in standard form.

Well if on the exam paper, it says something like 6.023 x 10^23, then he should know what that means.



(actually it's more likely you'd see that on a chemistry paper :P)



A calculator is no subsitute for understanding.

A calculator is no subsitute for understanding. [/QUOTE]True, true. Standard form is simple, though. If someone can't get to grips with it quickly, they probably shouldn't be doing physics anyway. :P

Instead of 1,000,000,000, for example, you might see 1x10^9, ie a one with nine zeroes after it.

f = ma
[QUOTE=''comp_atkins'']f = ma[/QUOTE]Gotta love those formulas. 
[QUOTE=''comp_atkins'']f = ma[/QUOTE]Pfft, v=u+at is where it's at.
