Some people that get on a bus get motion sickness. Some people are fine while riding.
The boy will fall in the direction of the bus's motion due to inertia. As the bus moves forward, the boy's inertia will keep him moving in the same direction until gravity pulls him back down.
because in the bus we are in motion and as soon as we move out there is sudden jerk because of inertia of motion.
Yes, a bus in motion possesses kinetic energy due to its movement. Kinetic energy is the energy an object possesses due to its motion, and in the case of a bus, it is moving so it has kinetic energy.
Your friend appears to be at rest because they are in the same reference frame as the bus. Since they are moving at the same speed and direction as the bus, there is no relative motion between them and the bus, making it seem like they are at rest.
If a passenger on a bus moving east sees a man standing on a curb from the passenger's perspective, the man appears to be moving west at a speed equal to the bus' speed.
When a bus starts moving forward, the inertia of the body tends to resist this change in motion. As a result, the body leans backward in reaction to the bus acceleration before adjusting to the new motion.
Inertia. A body in motion will remain in motion unless acted upon by an outside force. The motion of the bus is stopped by the brakes. The person inside keeps moving as it is not being braked.
The passenger jerking forward when a bus suddenly stops can be explained by Newton's First Law of Motion, also known as the law of inertia. This law states that an object in motion tends to stay in motion unless acted upon by an external force, such as the sudden stop of the bus which causes the passenger to continue moving forward.
When you are inside a moving train or bus, you are moving at the same speed as that train or bus, and you have the same momentum, so even when you jump, and are no longer in contact with the floor, your existing momentum will carry you along with the vehicle, under normal circumstances. If you happen to jump at a time with the train or bus is changing the speed or direction of its travel, however, you will find that you do not stay in the same place, with respect to the train or bus. You need to have solid contact with the vehicle for its own changes of motion to alter your own motion.
According to Newton's first law of motion, an object in a state of uniform motion will tend to stay in that state of motion until acted on by an external force. So, using this principle let's consider the case of a person on a bus. When you are standing on the bus, you are moving in the same direction with the same speed as the bus. When you jump up, the only force acting on you is gravity, which only affects your up-down motion. Assuming the bus is moving on a flat surface then, there are no forces acting on you in the direction of the motion of the bus to change your motion. Thus, you keep the same motion that the bus has, and you will stay in the same place relative to things inside the bus. There are situations in which this wont work! Consider, for example, what would happen if the bus made a sharp turn after you had jumped into the air. In this case, the some force has caused the bus to change direction, and so change its motion. However, since you are in the air, this force doesn't act on you. The result is that you will feel like you are moving relative to things inside the bus! Another related example of Newton's first law is when you jump on an elevator. If you jump just as the elevator is reaching the top, you will feel like you have jumped very high! This is because when you jump, you have the upward motion of the elevator, in addition to your jumping motion. When abraking force acts to slow the elevator down as it's reaching its destination, you avoid that force since you're in the air.
The person in front of you appears to be at rest relative to the bus in terms of their position and speed. They are moving with the bus at the same velocity, so to you both it seems like they are at rest even though the bus is in motion. This is due to the principle of relative motion.
When a passenger jumps out of a moving bus, they are still traveling at the same speed as the bus for a brief moment. As soon as they leave the bus, they are no longer supported by its frame, causing them to continue moving forward due to inertia. This forward motion causes them to fall face downwards due to gravity acting on their center of mass.
