| Description: | This applet allows the user to select different forces and masses. The force, in the form of a walking M&M, imparts an impulse to a mass and the mass slides on a surface. A PARAM tag controls the amount of frictoin on that surface. In the case of zero friction, the applet recovers F = MA. A graph automatically plots the kinetic energy, velocity and position of the sliding mass as a function of time. Gauges also read out this quantities in real time. Depening on the amount of friction, given forces can or cannot push given masses off the "end". This applet helps the user answer questions: - What is the behavior of the velocity in the case of zero friction? - What are the ratios of the three masses? - What combination of force and mass gives the maximum Kinetic Energy to the mass and what is this value? - What combination gives the minimum Kinetic Energy to the mass and what is this value? |
