When a bus starts suddenly, a person standing in it falls backwards.

Question

Verified by Toppr

Answer 1

When the bus is at rest, there is inertia of being at rest i.e. inertia to avoid motion.
Therefore when the bus starts suddenly, this inertia tries to keep the person in the same position as it was earlier i.e. at rest.
In this case foot of the person moves forward while the upper part of the body(like head) remains constant and person falls backward.

When a bus starts suddenly, a person standing in it falls backwards.

It is due to inertia of rest.

A man getting down from a running bus falls forward :

You are thrown ahead when your car suddenly comes to a halt and you are thrown backwards when your car rapidly accelerates. Which law of Newton is involved in this?

You are thrown outside when your car suddenly takes a turn. Which law of Newton is involved in this?

A block of metal is lying on the floor of a bus. The maximum acceleration which can be given to the bus so that the block may remain at rest, will be:

A person carries a hammer on his shoulder and holds the other end of its light handle in his hand. Let $y$ be the distance between his hand and the point of support. If the person changes $y$ , the pressure on his hand will be proportional to:
