Hello,

I'm experimenting with Gazebo Classic v11.10.2 and friction coefficient. I added a unit sphere, set the mass to 120kg, and the mu1 and mu2 coefficient to 0.0. Then I apply a small torque (eg. <500 N.m) around the X axis through the GUI "Aply Force/Torque" According to the GUI plot, I can see the torque is applied during 1s.

The sphere moves slightly during about 1s then stop (I can observe this by plotting the position or the speed in the GUI). As I set the friction coef to 0.0, I expected the sphere to spin endlessly, without translating. However, if I applied a high torque (5000 N.m), the sphere spins endlessly at constant speed.

Why is the frictionless sphere stopping for small torques ? Thanks
