10-Minute Review for AP Physics 1

As AP exam season is upon us, I wanted to do a quick summary of the major topics in AP Physics 1 and what you should keep in mind. Here's...

On the ap physics 2 first frq part cii where the angles are ranked, I believe that angles 1 and 3 cannot be equal as the angle of incidence in angle 3 is lower than in angle 1 making angle 3 smaller than angle 1.

You guys should take my suggestion and actually work out the math. I get that yes angle 2 will be less, but the difference in index of refraction is less too. Here I worked out the math for you with specific numbers I made up. But it'll work for any values of index of refractions and angles.

Could question 2-C on AP physics 1 talk about rotational inertia of the wheels, thus making the cart accelerate slower? Would that have been what they were looking for?

It's possible. However, the rolling of wheels like that implies friction is present. And they didn't want you to talk about friction.


So if they wanted that as a reasoning, I think they should not have had you exclude friction as something you can talk about.


The rotation of the wheels is probably what they wanted you to factor in. But I have a problem with the exclusion of friction.

The pdfs uploaded under AP Physics C: Mechanics are the pdfs for AP Physics C: E&M, not mechanics.

Thanks. I fixed that.

also, in the 3e of set 1 for E and M, isn't there charge on capacitor 1 causing a voltage drop.

Hi. I was looking at your solution to set 1 of the E and M guide, and correct me if I'm wrong but isn't the capacitance of capacitor 2 2c. I don't see where you took that into account

Ohh you're right. You're talking about how I didn't carry over the 2 in my work:
