Why Body Sensor give me non zero position curve but zero velocity?

Hi,

I have a simmechanic model, I connected a body sensor to the body which is moving. When I sense the position, I have a non-zero curve but when I sense the linear or angular velocity and accelerations,I get zero curves!

Why is that?

I found the problem,

I was defining the motion but I was only defining the position signal, then I added the velocity and acceleration signals, I started to get other signals as well!

Thanks for the question.. i have the same problem... How to give the velocity and identfy the moving and distance from the instial postion...???
