Why ball thrown upwards from the person standing on the top of moving train falls behind the person and not in the person's hand?

Why ball thrown upwards from the person standing on the top of moving train falls behind the person and not in the person's hand?
Question asked by: rajeshaj

Asked on: 17 Aug 2009

This is because the train that contains the person keeps on moving whilst the ball is in the air, the ball does not move relative to the earth however so whilst the train does the ball does not.

The net effect of this is that the person who is in the train has moved laterally whilst the ball has not, therefore it falls on the tracks (which is not safe by the way so don't try it for real!)
