Answer:

This phenomenon is due to inertia.

Newton’s First Law of Motion states that an object can either be stationary or travelling at a constant velocity unless it is acted on by an external force.

When the bus was stationary, its passengers also remain stationary as no other external forces were acting on it . It is only when the bus speeds up that the engine exerts a force which causes it to accelerate. (Newton’s Second Law: F = ma)

When the bus moves, all its passengers move in the same direction as the bus. However, humans have a tendency to resist that change in motion, that resistance is called inertia. So when the bus accelerates forwards, its passengers will want to remain to its original state of motion which was being stationary, that is why they are thrown backwards.

Answer:

this is due to newtons first law. it says that an object will continue to be in rest or motion unless an external unbalanced force acts upon it. examples are when we switch off a fan it still rotates. same way people r in motion with the bus but when brakes r applied, it causes a sudden movement because an unbalanced force acts on us as we were moving
