Well I Never!

Another myth, methinks.

For a start, there is the curvature of the earth to consider and possibly the aerodynamics of a spinning bullet may influence the speed that the bullet falls to earth.

I'll await Foxy's thoughts on this one.:whistle:

The laws of physics and gravity are a pain in the backside.

Galileo? He was the original 'Falling Bodies' guy.

Muskets and Cannons were certainly around in his time.

Galileo thought the dropped bullet would land first. Newton went for together, but surely it must depend on the felocity of the bullet that is fired from a gun.:confused:

Are you sure Galileo thought that way?

Why would it depend on velocity?

It could, however, depend on what it hits along the way! :rolleyes:

I thought Galileo took into account the curvature of the earth ? A bullet fired a short distance would not be affected, but one fired with enough velocity would be. I may well be wrong, as it was a couple of years back when my daughter was doing her Physics A level, that we discussed it.

Earth was flat in his day! :whistle:

Though I don't believe the curvature of the Earth is significant - certainly not measurable over the distances involved at the time! Remember that they were only accurate up to 150 yards too!
 
If you had a long enough flat surface to experiment on, a beam of light would also hit the ground at the same time as the dropped objects.
 
The GPS system only works because it allows for the fact that time ticks at a different rate on the orbiting satellites than it does here on the ground.

If that fact were ignored, by the time you'd finished the front 9 your GPS would be wrong by 1,000 yards.

That might explain where some of the forum distances come from!
