A2 practical: Spinning stopper (GeoGebra)
In this exercise a simulation of the spinning stopper will be built by first resolving the forces to give the angle of the string for different values of mass and length, then the stopper will be animated by applying the equations for circular motion. From the free body diagram we can see that the vertical forces are balanced, this means that Tcosθ = MgBut T = mg So, mgcosθ = MgBut cosθ = h/L So mgh/L = Mg h = LM/m...
