Demo: Newton's First Law Using Smart Fan Carts

Two Smart Fan Carts attached by a string oppose each other with no net force, sitting still. Then two Fan Carts oppose each other with no net force but give them a pull and they travel at constant velocity. Finally, one Fan Cart is given twice the thrust as the other Fan Cart and the two carts accelerate in the direction of the cart with the greater force. However, the forces of the string on each cart are equal and opposite.
