Purchased but have NO ACCESS?! I purchased this AND the chemistry app in may and June of 2011, and now it tells me that I have to purchase the app again....what's the deal?!
Nothing special Must purchase after 1st mini-lesson. They describe it as fun, but they didn't design in anything fun. Stock with Kahn.
App Stopped Videos won't function.
Not Bad This is not a bad app at all for reminding you of some of the physics you may have forgotten. There were no in-app purchases which I could see. All topics were accessible. I subtract one star for limited dept of coverage and for having to register. Note that a bogus email will work.
Good app for learning or demonstrating the fundamentals of Physics
App now has videos and require in-app purchases.
