As the title says, how much explanation do i need for:
1)AP physics B free response
2) AP calc BC free response

I'm going to show the work leading to my answer of course, but for physics specifically, I heard that you need to put explanations like "conservation of momentum" next to your work to get full credit. Is that true? Any help is greatly appreciated!

For calculus, your work is good enough for "justify your answer." However, if you are testing convergence, you need to include "convergent by ratio test"; you need to specify what you did.


The best way to see what you get credit for and what you don't get credit for is to check the scoring guidelines collegeboard posts and see what they give credit for.

AP: Physics B

AP: Calculus BC

In Physics, I am pretty sure that if you do something like m1*v1 = m2*v2, they'll understand that as conservation of momentum.

You can also do Utop = KEbottom to show them that you want to do energy conservation.

Definitions also help. F= delta KE (I think?) W=F*d etc.
