Rockets Concept

Demonstrates rocket propulsion via Newton's Third Law and conservation of momentum. Expelling gas in one direction accelerates the cart in the opposite direction, showing that rockets need no external medium …

A toy water rocket demonstrates rocket propulsion via conservation of momentum. Pressurized air expels water downward; the rocket accelerates upward — a dramatic, memorable example of Newton's Third Law.

A balloon on a low-friction cart demonstrates rocket propulsion via Newton's Third Law. As air is expelled backward, the cart accelerates forward, illustrating momentum conservation in a variable-mass system.
