When a moving bus suddenly stops a person sitting?
When a fast moving bus is stopped suddenly, the passengers sitting in it tend to fall forwards. This is due to. inertia of rest.

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.
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.
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.
Initially, the passengers and the bus both are moving in same direction. When the bus suddenly takes a sharp turn, the lower portion of passengers which is contact with the bus tends to move in that direction but the upper portion of the passengers throw an outside. This happens due to the INERTIA OF DIRECTION.
The correct answer is Newton's first law. ?Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by force. This postulate is known as the law of inertia.
Expert-Verified AnswerIf the bus suddenly moves going to North or forward, the passenger will tend to move backward or South. The passenger's movement is in opposite direction to the bus. The reason behind this one was because of the inertia in motion.
Inertia of direction is the property of a body due to which it maintains or tends to maintain its direction of motion. Due to this property, when a bus takes a turn, passengers are thrown away from the centre of the curved path because the passengers tend to maintain their original direction.
