Bring Newton’s three laws of motion to life with this DVD that uses extraordinary slow motion HD footage filmed during car crash testing to explore how energy is distributed during the fractions of a second when cars crash. The DVD explores ideas of inertia, resultant forces, energy and momentum, but applies it in the real world context of designing air bags, crumple zones and seats to protect the passenger.

In this video, we will begin our study of the Kepler problem, in which two masses move under an inverse-square law, namely the law of universal gravitation. We will derive the equation that needs to be solved and also talk about two conservation laws: angular momentum (geometric algebra perspective) and the conservation of energy. References…
