An Experiment of Relative Velocity in a Train Using a Smartphone
Priyanto, Aan; Yusmantoro; Aji, Mahardika Prasetya
Physics Teacher, v58 n1 p72-73 Jan 2020
When we travel in a train moving at a certain velocity, we observe the stationary objects outside are moving backwards. These stationary objects seem to move due to a relative velocity. Consider that the stationary object outside the train is a man standing on the stationary floor watching a woman moving on a train. The woman on a train will see the man moving backward with similar velocity as her. In kinematics, this magnitude of relative velocity will always be the same whether the man is far away from or near the train, as long as he stands on the stationary floor.
