Intro Page

Misconception of Students

·       Objects slow down in the presence of friction or air resistance.

Outcomes of the simulator

·       Students can visualise how motion is affected when Fnet > friction, when Fnet = friction and when Fnet < friction, while the cart remains in motion.

·       Students learn how to predict motion given the magnitude and direction of Fnet with relation to the direction of motion.

For Teachers




Video by ETDtogo explains why the simulation fan produces a (point to the right) forward force. In the YouTube video, the cart moves to the left because the exhaust gases from the fire extinguisher pushes to the right.
