Explanation:
When a bus is in motion, all the objects inside the bus, including the passengers, are also in motion. This is due to the inertia of motion, which is the tendency of an object to resist a change in its state of motion.
When the bus stops suddenly, two forces come into play:
1. The force applied by the brakes of the bus to bring it to a stop.
2. The inertia of motion of the passengers inside the bus.
Inertia of motion:
The inertia of motion causes the passengers to continue moving forward with the same velocity as the bus before it stopped. According to Newton's first law of motion, an object in motion tends to stay in motion with the same speed and direction unless acted upon by an external force. Therefore, when the bus stops suddenly, the passengers inside the bus tend to keep moving forward due to their inertia of motion.
Force exerted on the passengers:
When the bus stops, the force applied by the brakes brings the bus to a halt. However, the passengers inside the bus are still in motion due to their inertia of motion. As a result, the passengers experience a jerk or a sudden backward movement as their bodies tend to resist the change in motion.
Effect on the passengers:
The jerk experienced by the passengers can be uncomfortable or even cause them to lose balance momentarily. This is because their bodies are abruptly decelerated when the bus comes to a stop, while their inertia of motion tends to keep them moving forward.
Conclusion:
The jerk experienced by people sitting in a moving bus when it stops is due to the inertia of motion. The passengers tend to keep moving forward with the same velocity as the bus before it stopped, and the sudden deceleration of the bus causes a backward jerk.

When the bus stops, the people sitting in it experience a jerk. This is because, while the bus was moving, the people were moving with it. Hence, they were having an inertia of motion. When the bus stops, the inertia of the bus changes from that of motion to that of rest. But the inertia of the people still remains that of motion. Hence, they experience a jerk.
