Expert Answer:

When a passenger in sitting or standing in a stationery bus, both the bus and the passenger are at rest. When the bus starts moving suddenly, the lower part of the passenger’s body starts moving forward with the bus. The upper part of the body tends to remain in the position of rest due to its inertia of rest. As a result, therefore, the passenger falls or leans backwards as the bus starts.
