Teachers and homeschool parents can quiz their students on the motion of balls with a new series of free YouTube videos from Schottenbauer Publishing.
These videos can be watched before and after three tutorial videos, showing 24 real sport balls bouncing, rolling, and flying through the air in projectile motion.
The latter three videos correspond to the Sampler Edition of Bounce, Roll, & Fly: The Science of Balls. This and other books by M. Schottenbauer, Ph.D. are available in both English and German from Amazon, Barnes & Noble, Books-a-Million, Powell's, and other internet retailers. Wholesale is available directly from CreateSpace online.
