 8. A passenger standing in a bus at rest is jerked backwards when the bus starts suddenly. Why? Give reason.

Reason:-

The lower part of the passenger's body is in close contact with bus. When the bus starts moving, the lower part starts to move at once. But the upper part try to maintain its state of rest due to inertia. So the passenger standing in a bus at rest is jerked backwards when the bus starts suddenly.
