Hello! Well, I am in trouble with this question for some time. I am making a simulator with autonomous cars and its movement is done applying constant impulses to the wheel. My question is: if the vehicle is in the intertia state and I start to apply this impulses, the vehicle will assume a constant acceleration? In my simulation, the vehicle begins with progressive increases in acceleration and only after some time the acceleration keep constant. But I know that it is a perfect system because when I set 0 impulse after some time, the velocity keep constant. This can occur due to the moment of inertia of the wheel ?
