How to determine whether you are moving in constant velocity without any reference?

  1. Mar 14, 2006 #1
    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.
