do you? :
a: land in the same place you jumped from
b: end up somewhere further towards the middle/rear of the bus because it was moving?
-------------------------------------------------------------------
sense or confusion i do not know as i have never tried it and am not a physicist
rest assured someone will know the answer, or will go and try it out to find out the answer
p.s. i know that you should stay seated whilst the bus is in motion, but in this case there will be an exception for scientific reason
you'll land back where you were because your moving at the same speed as the bus (40mph) unless of course the bus rapidly accelerates/decelerates while you're in the air then you'll land in a place further back/forward respectively.
whether the bus is moving or not the floor your standing on isnt. just like a pavement so it would be the same
did you take into consideration that the bus weighs approx 7.5T and a human will be around 12st average
and the floor of the bus will be moving, the same speed as the bus
40mph as said
i dont know of any pavements that do 40mph
Wrong. If the bus is at a constant speed, and you jump up you will begin to decelerate in your forward motion. This means you will land a little further back from where you started as the bus is still at 40mph. The higher you jump, the further back you will land. Jump high enough and you won't even land on the bus
i could understand that if it was an open topped vehicle because u would have wind resistance affecting u, but inside i dont think it affects u, if u could get a glass box on a miniture railway travelling at 30mph and have a ball released from the top of the box to the bottom with a camera tracking movement then it would get u an answer, to see if the movement is enough to effect the pull of gravity
