Bullets and Gravity
Discussion
On the BBC home page, which I glance at before starting work, this caught my eye. it was in the QI section...
'A bullet fired horizontally from a gun, and a second bullet dropped by hand from the same height as the gun, will both hit the ground at the same time. The forward motion of an object has no effect on the pull of gravity.'
Ran the idea through my head... and whilst I am no genius or scientist (and do not have any conveyor belts handy), it just doesn't seem 'right'. Surely the fired bullet has two forces being applied, both the force from the 'firing' of the bullet, in the horizontal direction and the gravitational one. Just struck me as a mildly interesting fact...
(Can't really demo it in the kitchen, as the wife keeps getting in the way... if she buggers off, will report back findings)
Back to work now...
