what's it like physics with calculus? how hard is it?

Question

I am currently taking AP Physics and AP Calculus. So far AP Physics B(without calculus) is easy I have an A. However AP Calculus AB I have a B in there. Is physics with calculus in college a combination of the two, say using integrals from calculus and momentum from physics or something similar?

Answer 1

Much electrical theory and mechanics (classical and quantum) define potentials, and give forces in terms of differentials. The area of maths you need to know is Limited and could be learned quickly.
You will also deal with vector differentials of potentials which are a lot harder.
Nobody can answer the 'hardness' question for you.
Look at degree level books on electrical theory and mechanics (classical and quantum) and judge it for yourself. Get hold of the course outline and old Examination Papers from the universities when you apply to them.
A physics degree is hard work, and you will need a good grade at the end to enter interesting work.
