why is it dangerous to jump out of a running bus?

answered-by-expert Expert Answer

According to newtons ist law of motion Every object has inertia , and it will try to avoid the change in its interia.
When you are in bus, u are moving with the velocity of bus with respect to ground. So you have the interia which can be understood as your momentum in this case. So when u jump out of a bus, u change your speed from a finite value to zero instantaneously, which causes an abrupt change in momentum, which your body will try to resist. So your upper body will still be in motion while your feet are still. It means you will definitely fall down.
