Why do pesenger in a bus tend to fall backward when it starts suddenly

1.	Why do pesenger in a bus tend to fall backward when it starts suddenly.
Answer» DUE to INERTIA of our body. In CASE of bus there are two SITUATIONS 1: when the bus STARTS we go backwards because our state of inertia is tend to be at rest the bus starts immediately and our body's state of inertia is disturbed the result we go backwards. 2: when the bus pulls the break. Our body moves forward this is because when the bus is moving our state of inertia is tend to be moving but because of an immediate break the inertia is disturbed the reason we move forward...
