  1. Clicker questions for Ramp- Force and Motion activity 1 If you want to make questions like I have where only one variable changes and you see what changes on the diagram: Play with the sim until you get a diagram you like. (you can go pass the spot) Pause the sim. Use the vertical bar to go back to a spot that you liked, then you can change variables (hit enter to make the change take place) and the changes will show on the diagram without having to run the sim.
