Question

a passenger in a moving bus is thrown forward when the bus stops suddenly this is explained by Newton's which law
​

Answer 1

when a moving bus stop suddenly passenger thrown forward because inertia of motion ( Newton's first law of motion), lower part of body comes to rest but upper body tend to maintain uniform motion. hence passenger thrown forward

please follow me

Answer 2

Passenger thrown in forward direction on applying brakes in a bus is explained Newton's First Law of motion.

Explanation:

• Newton's first law of motion states that " An object remains in a state of rest or of uniform motion in a straight line until an external force is applied to change the state".
• For example, when a bus driver suddenly applies break, passengers are thrown in the forward direction.
• The simple reason for this is inertia of motion. Since, when the bus is running in its average speed, lets say 60 km/h , then the passengers in the bus are also travelling in the same speed.
• Once the driver applies break, the state of bus changes from motion to rest. But on the other hand, the passengers are still in the same (60 km/h) motion.
• Hence, to compensate the relative difference in velocity factor, passengers are thrown in the forward direction.
• Newton's first law of motion is also called as Law of Inertia.
• Some other examples of Inertia are dusting a dirty mat. Shaking the tree for the fruits to fall . All are due to change in the state of their relative original state.
