We make this adjustment so that the second wheel stops. If you set "Angular Friction = 0", you will see that the wheel continues to spin. "MSPhysics_v1.0.3" does not work properly yet. Author Anton_S is working on the new version. The new version has been released yet. For more information see here. https://sketchucation.com/forums/viewtopic.php?f=323&t=56852&start=840
