1. The problem statement, all variables and given/known data When a car turns or accelerates, you feel and extra force, and some hanging things in the car also shift. How do you explain this phenomena? 2. Relevant equations 3. The attempt at a solution My explanation was simply that since the car is a non inertia frame of reference, you experience an imaginary force that pushes you away from the the direction you're turning/accelerating in. You tilt when turning because friction and your new weight exert a torque on your body. My friend's explanation was that you are "feeling inertia" I do not know how to explain why I think "feeling inertia" is an icky explanation, could anyone explain why this explanation may be right or wrong to me? My friend and I also had issues with the concept of "feeling an imaginary force"
