If you are riding a car, would you be in motion?
Yes, the motion of the car is imparted to you. If the car stops suddenly your momentum will carry you forward, into the dashboard, windshield, etc. This is why seat belts and airbags are so important.
Since motion is considered as any movement or change in position, then I think driving would be a motion. It involves the movements of body part, when controlling the wheel.
yup, though earths in motion so your already in motion
yes, because you are moving with the car
