Conservation of Momentum Derivation and Rocket Demonstration

Newton’s Second Law in terms of Momentum is introduced and used to derive Conservation of Linear Momentum. A water rocket in slow motion is used to demonstrate this as well. Want Lecture Notes? http://www.flippingphysics.com/conser... This is an AP Physics C: Mechanics topic.

Also, all of my 2 liter bottles had an opening which was to small to fit the 1/2” PVC pipe. So, I warmed the neck of the 2 liter bottle in boiling water and fitted it over the 1/2” PVC pipe to stretch the opening to fit. 😀
