# Unity – How can I predict the angle at which a wheel will stop spinning?

In my 2D game, I have a spinning wheel using the rigid body function `_rb.AddTorque (_torque)` that I'm calling in FixedUpdate. Still in FixedUpdate, I limit the angular velocity of the wheel so that it does not exceed a certain value. When the wheel has finally reached its maximum angular velocity, I set the torque to zero so that it stops slowly

``````Private void FixedUpdate ()
{

if (_rb.angularVelocity> = _maxAngularVelocity)
{
_rb.angularVelocity = _maxAngularVelocity;
_torque = 0;
}
}
``````

The wheel turns exactly as I wish, but is there a way to predict the exact angle at which the wheel will land before the end of rotation? I do not know much about physics, but if anyone can give me the general formula, I can try to implement it in the code myself.
