The people in a bus are pushed backwards when the bus 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 the upper part of the body has a tendency to remain in the state of rest due to inertia of rest, and hence falls backwards.

The people in a bus are pushed backwards when the bus starts suddenly ...
Explanation:
When a bus starts suddenly, the people inside the bus tend to move backwards. This phenomenon can be explained by the concept of inertia. Inertia is the tendency of an object to resist any change in its state of motion. According to Newton's first law of motion, an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.
Inertia due to Rest:
The correct answer to the question is option 'D' - Inertia due to rest. When the bus suddenly starts moving, the people inside the bus were initially at rest. As a result of their inertia, they tend to remain at rest even when the bus starts moving. Therefore, when the bus accelerates, the people inside the bus are pushed backwards.
Explanation of Other Options:
- Inertia due to Direction: This option is incorrect as inertia is not directly related to the direction of motion but rather to the tendency of an object to resist any change in its state of motion.
- External Force: This option is incorrect as the people in the bus are not pushed backwards due to any external force but rather due to their own inertia.
- Inertia due to Motion: This option is incorrect as the people in the bus were initially at rest and it is their inertia due to rest that causes them to be pushed backwards.
In conclusion, the people in a bus are pushed backwards when the bus starts suddenly because of their inertia due to rest. They tend to remain at rest even when the bus starts moving, resulting in their backward movement.
