Investigating Thrust and Rolling Resistance with the Motion Encoder System and Fan Cart

Free-body diagram—Encoder Fan Cart speeding up under the influence of the thrust from fan

Richard Born (Northern Illinois University) has developed a great lab using two of our products, the Encoder Fan Cart and the Motion Encoder System. In this investigation, he has students measure the forces on the cart (fan thrust and drag) and the mass of the cart/fan system and predict the acceleration.
