here's a gravity one
-------------------------------------------------------------------
if youre standing in a bus at the front next to the driver
> and the bus is travelling at 40mph
> you then take a jump (directly upwards)
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
