Should i wait a year or so and take AP physics or take physics over the summer, at a college just asking(am a freshman in high school)

The only reason I ask is that I'm in both classes (AP Physics C:Mechanics/AP Calc BC) and I find myself using formulas from one class to answer the question in another class. I did one question in Calc involving the motion of an object and used some physics formulas to solve it. The work for...

I was reading the Princeton Review AP Physics B book and i don't understand the concept of diffraction. Can someone please explain it to me?

Hi everyone! I was going to post this in the coursework section, but was quickly alerted by the text template requiring me to elaborate upon my problem, hehe. If this is the wrong section, you may of course close/move this thread. Thanks! In any event, I have a few questions about AP...

I'm a senior currently taking AP Physics C: Mechanics and really like the class, and am thinking about majoring in it in college. However, I know that college math is nothing like high school math. Is college physics similar to AP Physics C?

I signed up for Physics B because my teacher said it was broad and could help me in getting an engineering degree. I actually found out that a lot of schools don't accept AP Physics B for college credit. MIT accepts credit for AP Physics C if there is a 5 on both exams. It's too late to...

I'm currently a Junior in high school with an average GPA of about 3.197 (includes first semester of Junior year). Over the years, I haven't really been taking hs TOO seriously due to the lack of focus and effort in my studies (and also because I thought high school would be as easy as middle...

I am currently a junior in high school taking physics A. I find it very easy and natural and have an A for 1st semester and a 97 on the midterm. I want to take AP physics but i am not sure which one. In college i am most likely going into construction so I will need a lot of math and physics...
