Determining Motion in Windowless Train: Is It Moving or Stationary?

In summary, when riding in a windowless train, it is impossible to determine if the train is stationary or moving at a constant velocity without detecting something outside. This is because motion can only be described in relation to another object. Therefore, being at rest and moving at a constant velocity have no difference when there is no external reference point.

Say you are riding in a windowless train that is either stationary or moving at a constant velocity with respect to earth. How can u determine whether you are moving or not? I cannot think of a way since u would feel anything unless the train accelerates right? Thanks to whoever reply :rolleyes:

That's the whole point. You can't and there is no way you ever will without detecting part of what's going on outside. Motion can only be stated with reference to some other object. If there is no "other object" then there is no difference between being at rest, and moving with constant velocity.

that makes sense. thanks a lot chi!
 

FAQ: Determining Motion in Windowless Train: Is It Moving or Stationary?

How can we determine if a windowless train is moving or stationary?

To determine if a windowless train is moving or stationary, we can rely on a few key factors. One way is to look at any surrounding objects or landmarks outside the train. If they appear to be moving past the train, then it is likely that the train is in motion. Another way is to feel for any vibrations or changes in acceleration, which can indicate that the train is moving.

Can we use our sense of balance to determine if the train is moving?

Yes, our sense of balance can also help us determine if the train is moving. If we feel a slight sway or change in our balance, it can indicate that the train is in motion. However, this method may not be as reliable as using external factors or instruments to determine motion.

Is there any way to measure the speed of the train without windows?

Yes, there are various instruments that can measure the speed of the train without windows. These include speedometers, GPS devices, and other motion sensors. These instruments can provide accurate readings of the train's speed and direction of motion.

What role does Newton's first law of motion play in determining the train's motion?

Newton's first law of motion states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force. This law can be applied to determine if the train is stationary or in motion. If the train is not experiencing any external forces, then it will continue to move at a constant speed, and if it is at rest, it will remain at rest.

Are there any other factors that may affect our perception of the train's motion?

Yes, there are other factors that can affect our perception of the train's motion. These include the design and layout of the train, as well as the smoothness of the ride. For example, a train with a curved or winding track may give the illusion of motion, even if it is stationary. Similarly, a bumpy or rough ride may make it difficult to determine if the train is moving or not.
