Physics Problems

I agree with your suggestion.

Yes, it would be great to have as much practice material with physics as we do with math.

I also think that is needed.  How can my son take a class in physics if there is only one problem per topic? (If there are more that that, I can't tell.  There is no way for me to look without answering the question to see if it will move me on to another under the same topic.)
