1K20.11 - Tug of War
Video Credit: Jonathan M. Sullivan-Wood.
Connect the two cars together using the Plexiglass connector. If the two cars are equal masses and have the same motor speed they will pull against each other with equal force. Add a small mass to either of the cars and the increased friction will allow that car to win the tug-of-war.
The two cars can also be connected together facing each other to show the same effect in a pushing mode.
