Why do passengers in a bus moves forward as soon as the bus stops?

Question

NEWTONS THIRD LAW OF MOTION

Answer 1

If they are in that bus, which is moving, then they were *already* moving forward, duh. They better be, if they were in a bus that was.

The bus slows down, well they were already moving forward, they still are, nothing stopped them but the inside of the bus and I hope it was gentle.

Answer 2

It is due to inertia, also known as the Newton's First Law: "A body in motion tends to stay in motion...."

When a bus is moving down the road at 20 mph, everything on it is moving at the same speed; the engine, the seats, the bus driver, the passengers, the contents of the passengers' pockets, etc.

So, when the driver applies the brakes of the bus, the bus and everything attached to it (the seats, the engine, etc.) also stops (assuming the bolts holding them down are strong enough).

Anything not screwed down (passengers, coffee cups, laptop computers, etc.) continues to move at 20 mph until something stops it; in the case of people, they either press their hand against the seat in front of them, grab a pole in the bus, fall to the ground, crash into the windshield, etc.

This also why seatbelt save lives - they hold the rider in the seat so that the brakes of the vehicle are stopping the rider too, rather than having him crash into the inside of the car or bus, or worse yet fly right through the windshield.

Answer 3

Inertia. Objects at rest tend to stay at rest, objects in motion tend to stay in motion. The bus may have stopped, but the people are still moving at the same speed for a few moments. That's the problem in a car crash. Car hits tree, tree over comes inertia, car stops. Passenger still going 70 mph until an outside force, like the windshield, the tree, another passenger, etc can over come that inertia.

Answer 4

Simple. According to th third law of newton, everything that is moving continues to moves, everything that stop remain that stop. In this case, you are in the bus moving. So, your body tell your mind that you are moving with the bus foward. As long as the speed is the same, your body will say to your brain stick that way. When the bus stop, the momentum when it stop moves you foward. This happen when your body thinks that the bus is still moving foward. So the body continue to move foward untill the mind figure something wrong happening then you will hold on to something so you will stop.

Answer 5

Inertia; since the passengers aren't attached to the bus, their tendency is to continue the original movement forward. Since the (negative) acceleration isn't that great, the passengers themselves overcome it by moving instinctively back, and remaining seated - at least, most of the time - until their motion matches that of the stopped bus, namely, none.

Answer 6

Wow, everybody so far is wrong.

The answer is "Inertia." An object at rest tends to stay at rest, an object in motion tends to stay in motion.

When the bus driver applies the brakes to the bus, then he is slowing down the BUS, reducing its forward momentum by use of friction. However, there is nothing stopping the people inside the bus. The force of the brakes is applied to the bus's wheels and everything directly attached to them, not the things that aren't (like people, or luggage).

So the people still have their OWN momentum. They eventually slow down as well because the friction between their butts and the seats holds their butts in place, but they still lurch forward a little bit because their backsides stay in place, but the rest of their bodies (which is flexible) bends a little bit before it slows down, too.

Answer 7

If I observed that incident take place in front of me, i could anticipate the three adult men have been ignorant and rude, as they have been. i does no longer mean that they did it by means of their skin colour in spite of the undeniable fact that. i've got considered various white people act this way too. it incredibly isn't any longer something to do with skin colour; the adult men in question merely surpassed off to be ignorant and surpassed off to be black. i do no longer think of the two aspects are appropriate. Your comments contained in the 'further information' tab in spite of the undeniable fact that time out that that's certainly you your self who has the undesirable ideas-set. the rationalization all of the solutions you're getting are asserting there isn't any relation between colour and the form you act is on the grounds that's genuine. Going faraway from that incident hating black people is ignorant; extra ignorant than how those adult men behaved. you should savour the incident for what it incredibly became, and not base people's movements on their skin colour. i'm white by using the way.

Answer 8

Momentum. Although the bus has brakes anything not fixed in the bus will automatically move forward, unless the driver slows down really slow.

Answer 9

Moment of Inertia

Answer 10

this is because they want to get off and think if they move forward towards the doors they will get off quicker, it must be so annoying to the driver, people are in a rush quite a lot these days and why can they not just step back and be a little laid back...because everyone gets off in the end..x
