I have a 5kg sphere and apply 100N of force in the +Z direction. Assuming lim t->0, the sphere should leave the ground at ~20m/s vertically and reach a height of ~41m. Instead it remains stationary. It will only hop if I apply outrageous amounts of force (1000N).
Does anybody know what's causing this? Even if the impulse is over half a second it should leave the ground. I see this even when I create a sphere primitive using the GUI, and apply force using the GUI.
