Why a person Travelling in a bus fall backward when it starts suddenly?

This is due to inertia of rest of upper part of the passengers body when the bus or train suddenly starts moving, the lower part of the passenger's body starts moving along with the bus or train while upper part of the body has a tendency to remain in the state of rest due to inertia of rest and hence falls backward.

This is because of inertia of motion. The part of our body, which is in contact with the bus, changes the direction of motion. However, the rest of the body tries to move in the same direction as before because of inertia of motion.

The correct answer is Newton's first law. ?Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by force. This postulate is known as the law of inertia.

You need to protect your head in some form.” For example, if you fall backward, tuck your chin and push your head to your chest to stop your head from having a violent collision with the ground. And if you fall forward, turn your face away from the ground and shield your head with your arms and hands if you can.

When the bus suddenly takes a sharp turn, the lower portion of passengers which is contact with the bus tends to move in that direction but the upper portion of the passengers throw an outside. This happens due to the INERTIA OF DIRECTION.

To recap, Newton's first law, the law of inertia, states the following: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted on by an unbalanced force.
