SUMMARY

Determining motion in a windowless train is impossible without external reference points. The discussion highlights that one cannot ascertain whether the train is stationary or moving at a constant velocity without detecting external objects. The fundamental principle established is that motion is relative and can only be defined in relation to another object. Therefore, in the absence of external cues, the state of motion remains indeterminate.

PREREQUISITES
  • Understanding of Newtonian physics, specifically the concept of relative motion.
  • Familiarity with the principles of reference frames in physics.
  • Basic knowledge of acceleration and its effects on perception.
  • Awareness of the limitations of sensory perception in determining motion.
NEXT STEPS
  • Research the concept of inertial reference frames in classical mechanics.
  • Explore the implications of Einstein's theory of relativity on motion perception.
  • Study experiments related to motion detection without visual cues.
  • Investigate the role of external references in determining velocity and acceleration.
USEFUL FOR

Physics students, educators, and anyone interested in the principles of motion and relativity will benefit from this discussion.

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!
