IMAGINE THAT A PASSENGER IS WALKING TOWARDS THE BACK OF A TRAIN AS THE TRAIN IS LEAVING THE STATION. WHY WOULD THIS PERSON'S DESCRIPTION OF THEIR MOTION DIFFER FROM THAT OF AN OBSERVER STANDING ON THE PLATFORM ?
Motion is a change in object‘s position relative to its
reference point and time. Motion is usually determined in terms of time, acceleration,
velocity, direction and displacement. Motion is monitored by connecting a frame
of reference to an object and computing its change in position with respect to
above scenario, Person B stood at platform is monitoring train and person A
walking behind it. For Person A the train is a frame of reference and person B
is an object. Person A description of motion differ from that of an observer
standing on the platform because he
is changing his position with respect to time but person B hasn’t changed his
position relative to time.
