I am working on kinematically modelling an accelerometer on a car wheel.
When working on the initial conditions, I am confused whether or not I should use the gravitational acceleration since there is a normal force reaction counteracting. I.e should a = [a0, 0 , -g]
Thanks for the help :) Yosef
My Go at it: What I was thinking of, is that in case I was modelling a point on the wheel, the gravity would not be considered. However when modelling the measurement of an accelerometer I should consider the acceleration. Probably I will need to shift to the equations of motions, which will make the whole story even more difficult.
