• AP Physics 1: Forces 1: Newton's First Law of Motion
• AP Physics 1: Forces 2: Newton’s 2nd Law of Motion, Weight and Force Demo
• AP Physics 1: Forces 4: Third Law of Motion Part 2: More Concept Questions
• Similar to the balloon rocket demo in this video, there is a Fire Extinguisher on a Tricycle demo you can find in the MIT PhysicsDemo -- Fire Extinguisher on a Tricycle. Just like the balloon shooting air out (and a rocket shooting exhaust out) to propel itself, the fire extinguisher shoots “stuff” out and uses that to propel the tricycle.
