Is your tennis suffering because of your poor physics knowledge?
Yes, that is a strange question, but this is the opening premise of The Manga Guide to Physics.
Megumi is distracted from her tennis match because she didn’t do well on her physics test (which coincidentally had a question about the forces involved when hitting a ball with a racket). Ryota, a fellow student who won a silver medal in the International Physics Olympic Games (?), offers to help her understand the material better.
