Plane Motion Produced by a User-Controlled Net Force
*Before start, the following changes may be made:
*Press "Start" to start the motion.
*The force "F" refers to the net force acting on the car.
.*Drag the yellow dot at the tip of the red arrow on th right frame continuously to change the net force applied to the moving car.
*A circular motion will be produced if the net force F is constant in magnitude and always perpendicular to the velocity (blue arrow).
* When the car goes outside, bring it back by adjusting the force such that the blue arrow (velocity) is pointing towards the white cross.
