A basic, inexpensive Fan Cart powered by two AA size batteries (not included) demonstrates Newton's principle of action and reaction. The batteries are contained in the removable power unit and the fan is controlled by a switch. The propeller delivers a thrust of about 88mN, accelerating the cart at 0.4 m/s2. A transparent plate can be attached to show the effect of reversing the airflow. Includes activity guide. |
