Will you move when you jump in the in side of a bus.?

Question

Like when you jump on the back of a truck in the trunk youll fall but wont you go back if you jump in the inside of a bus. if so why. And if not why.

Answer 1

You will not move.  The reason is that you are traveling at the same speed as the bus.  The only reason you would fall in the truck version is that wind resistance slowed you slightly.  If you were to jump at the same instant that the bus were to immediately stop, you would travel forward because you would still be traveling at the speed the bus had been traveling, or if the bus were to madly accelerate you would go backwards relative to the bus.
