EXPLAIN THE FOLLOWING:


1-When a train suddenly starts moving forward, the passenger standing in the compartment tends to fall backwards, why?

Ans-The reason is that the lower passenger’s body is in close contact with the train, starts moving , his lower part shares the motion at once, but the upper part due to inertia of rest cannot share the motion simultaneously and so it tends to remain at the same place. Consequently, the lower part of the body moves ahead and the upper part is left behind, so the passenger tends to fall backwards.
