Question

1. when are you most aware of your motion in a moving vehicle: when it is moving steadily in a straight line or when it is accelerating? if you were in a car that moved with absolutely constant velocity, would you be aware of motion?

Explanation:

In a vehicle, acceleration causes a non - inertial frame with forces acting on the body (like the push or pull when speeding up or slowing down), making motion more noticeable. In a vehicle with constant velocity (inertial frame), there are no additional forces due to acceleration, so motion may not be as perceptible without external references.

Answer:

You are most aware of your motion when the vehicle is accelerating. If in a car with absolutely constant velocity, you would not be as aware of motion without external reference points, as there are no acceleration - related forces acting on your body to signal a change in motion.
