To answer this question, we can look to Newton's first law of motion. Isaac Newton had many laws, but this question is related to the first law of motion. This first law of motion states that the body will remain still unless there is an outside force that acts upon it.

When you are on a moving bus, your body is normally at a still position, but when the bus stops, you will move forward. This is because the sudden brake and stop of the bus causes the passengers to change their position. Their body make jerk forward or they may just have their heard move

The reason is that the man is trying to resist the sudden change in his velocity. In other words, the man is only trying to resist the change in his motion so that it can maintain the inertia of motion. This happens most of the time when the driver of a car suddenly applies brakes, probably because he wants to stop an accident from happening.

When a vehicle moves with a particular velocity, all the objects in it will also maintain the same velocity. That said, any sudden change in the velocity of that vehicle will also have to affect all objects inside the vehicle.

This also agrees with Newton's first law of motion which states that an object will continue to move at a constant speed unless an external force acts upon it. A man in a moving vehicle is already having a constant speed until it suddenly stops due to whatever reasons, causing him to move forward.

Newton's law of motion can be used to help explain this. Newton had many laws of motions, but to best explain why a man sitting in a moving bus suddenly moves forward when the bus suddenly stops, we would want to look to the first law of motion. The law says that the body will continue to move at a uniform pace, unless there is an external force that acts upon it.

When it comes to people moving when a bus stops is because they already had a position that was uniform before the bus stopped. When the bus stops, the passenger's position changes, which makes the passenger move their heads.

The correct answer to this question is inertia. This is a law of science that explains motion. Furthermore, inertia has its own law of motion. This law states the following: “When the resistance is offered by the body to continue to be in the uniform motion unless an external force acts on it”.

The law inertia of motion helps explain why a person in a moving bus will move when the brake is pushed. The passenger on the bus tries to keep the inertia of motion. By them trying to do so, the force of the bus pushes him forward.

The main reason for this is because of the moving vehicle, in this case, the bus, and the man both have inertia. Since the bus has come to a sudden stop, the man’s body will still have the tendency to continue moving forward as this is the movement that it has grown accustomed to for some time.

If the stop happens gradually, the body will have enough time to adjust the amount of energy that it has. From rest, the body will move a bit forward but in a more cohesive manner as compared to a sudden stop. With the sudden force, the body experiences an unbalanced force.

The main reason for this is because of force and direction. The bus is moving which means that it is traveling at a certain speed because it does not have any plans of stopping. Yet, there are obstacles that may appear on the road that will cause the bus to suddenly stop by stepping on the brakes.

The sudden stop will cause the energy that is required to move to also stop and the force will be enough to bring the man forward. It would depend on the speed of the bus and the force of the stop to determine how strong the movement of the man will be. The stronger the force, the more likely that the man is going to move forward.

The reason for this can be explained using Newton's first law of motion. The law states that a body will continue to be in a state of uniform motion unless it is acted upon by an external force. The reason why people tend to move forward when a moving bus suddenly stops is that they have already maintained a uniform position before the bus suddenly stops.

And when the bus suddenly stops, it changes the position of the passengers. This causes passengers to move their heads a little bit forward depending on the acceleration the bus is moving with before it suddenly stops. A man in a moving vehicle is already in a state of uniform motion until his position changes when the bus suddenly stops.

However, this can cause the passengers in a moving car to move in any direction; it all depends on their initial position. Also, you might experience the opposite (a backward movement) if a bus suddenly starts.
