Answer to Question #76923 in Physics for Ramy
Question #76923
Even if you have very good balance, it is unwise to stand too near to the edge of a railway platform when a train is quickly moving past. Explain why, using Bernoulli’s principle.
Expert's answer
According to Bernoulli’s theorem, greater is the velocity; smaller is the pressure and vice-versa. Therefore, the air pressure behind the person becomes bigger than the air pressure between the person and the train. Due to this pressure differences, the force acts on the person towards the train.
