Why do passengers of a bus jerk forward when it stops suddenly?
This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.

When the running bus stops suddenly, the passengers are jerked forward because due to inertia of motion the passengers tend to remain in their state of motion even though the bus has come to rest.
Originally Answered: When the driver applies the brake suddenly, why does the upper part of the passenger jerk or move in a forward direction? The upper part of the passenger's body will appear to jerk forward because the lower part of his body is firmly attached to the seat of the car.
If I jump up in a moving bus will I land on the same spot where? If the bus is traveling at constant speed, yes. You're moving with the same speed as the bus, and you'll keep moving with this speed while you're jumping. If the bus is accelerating while you jump, you will land in a slightly different spot.
This is because of inertia of motion. The part of our body, which is in contact with the bus, changes the direction of motion. However, the rest of the body tries to move in the same direction as before because of inertia of motion.
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 upper part of the body has a tendency to remain in the state of rest due to inertia of rest and hence falls backward.
When a bus starts suddenly,its passengers tend to fall backwards because due to their inertia, the passengers tend to remain in a state of rest even when the bus starts moving.

When a bus takes a sharp turn, the person travelling in the bus tends to be thrown outwards towards the window. This is due to inertia of direction of the passenger.
