Draft:Fan and sail example

From Wikipedia, the free encyclopedia


A boat equipped with a fan and a sail

The fan and sail example is a situation studied in discussions of Newton's third law.[1] A fan is attached to a cart or a sailboat and blows on its sail. As a result, the vehicle may remain stationary or move into the direction of the fan's wind. A very common mistake is thinking that the forces in the system composed of the vehicle, the sail and the fan are all internal forces and, therefore, the vehicle can't move propelled by the fan in this way.[2][1][3] [4] [5] [6] [7]
