Question

Why is it advised to tie any luggage kept on the roof of a bus with a rope?

Answer 1

It is advised to tie any luggage kept on the roof of a bus with a rope because —

• A luggage is usually tied with a rope on the roof of buses. When a moving bus suddenly stops, the luggage on its roof remains in the state of motion due to inertia of motion. Hence the luggage falls down from the roof of the bus. Similarly, when a bus suddenly starts, the luggage on the roof of the bus continues to remain in the state of rest and hence falls down from the roof of the bus. Thus, to avoid the falling of the luggage, it is tied with a rope on the roof of a bus.

Answer 2

The luggage placed on the bus roof is not fixed to the bus. When the bus starts suddenly, the luggage tends to remain in the state of rest due to the inertia of rest. 

As a result, the luggage might fall towards the backside of the bus. When a moving bus stops suddenly, the luggage continues to remain in the state of motion due to the inertia of motion.

As a result, the luggage might slide towards the front side of the bus and fall. To prevent fall of the luggage from the roof of the bus, it is advised to tie the luggage with a rope.
