Physics, one tiny idea at a time

Short physics lessons for a young child and a grown-up to do together on an iPad. They follow the order of Richard Feynman's Lectures on Physics.

Sit side by side and read the big words aloud. The dark strip at the bottom is for you: tap Notes for you for tips and the physics behind each screen. Stop any time; the notebook remembers where you were on this iPad. To come back to this list, tap My Physics Notebook at the top of a lesson.
