When a bus makes a sudden stop passengers tend to jerk forward?
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 a bus or train at rest starts, to move suddenly, the passengers sitting in it jerk in the backward direction due to their inertia of rest.
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.
And the bus stopped suddenly. I fell down. Because of Newton's Law of Inertia, which states: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
