See how you can use two or more Cart Fans to explore how fan thrust affects acceleration, momentum, and kinetic energy of carts on a track This video provides a quick demonstration of the Cart Fan’s settings and a quick step-by-step guide for an opposing forces experiment using two cart fans on a Go Direct Sensor Cart. Students can explore how two forces reinforce or hinder one another, depending on their direction and magnitude. 

Drive student engagement with force and motion phenomena! With the Cart Fan, your students can investigate Newton’s laws and kinematics and dynamics with constant acceleration, variable mass, variable thrust angle, and variable thrust and duration at the push of a button.
