Question

How do people determine if a vehicle in which they are sitting is moving?

Group of answer choices
A.by comparing their position to a fixed object inside the vehicle
B.by comparing their position to a fixed object outside the vehicle
C.by comparing their position to a moving object inside the vehicle
D.by comparing their position to a moving object outside the vehicle

Answer 1

B.

Step-by-step explanation:

The only way to make this comparison is by comparing their position to a fixed object outside the vehicle. Comparing to a fixed object inside the vehicle will show no movement, while a moving object inside the vehicle will seem as though the car is still while the object is in motion. Comparing to a moving object outside the vehicle will conflict with the vehicle, if the object is moving at the same speed and direction as the vehicle, it will seem as though neither is moving. The only way to make this comparison correctly is by comparing to an object outside the vehicle that is not moving so that the only variable that can be moving is the vehicle itself.
