Terminal Velocity revisited... again!!

Recommended Posts

Hoping someone can help me out here as I stand to win £1,000,000 US $ - at least that was the bet, I may be settling for :D :D :D

Two spheres of equal size with equal surface resistance/drag.. one full of lead, one full of feathers, dropped from higher than the leaning tower of pisa i.e an aeroplane.. do they hit the gound together, or is weight/density/mass a factor. The lead ball will fall faster no? Why else would skydivers wear weights? And fuck dropping them in a vacumn..

Hope I don't stand corrected..

heavy ball smashes in first in normal
atmosphere.

You're correct, the lead ball will hit the ground first. Think of it like this: A balloon, and an equally sized/shaped/textured 50lb object are dropped at the same time. It's pretty obvious which one will fall faster. The whole "all objects fall at the same speed" thing ONLY applies to a vacuum when all conditions are perfect. Gravity applies the same force to all objects regardless of shape/size/texture/weight, but unless you ARE in a vacuum, you have to factor in all the other variables too :)

Hoover or Oster?

Thank you all..

The bet is based on real world through an atmosphere, hence why I said fuck dropping them in a vacumn, where elephants and feathers fall at the same speed.

Casch that was exactly the analogy I tried to convince them with - 2 balloons equal size etc one blown up with air, one full of water, which one will hit the ground first.. erm.. hello?!?!

I also tried to invert the equasion somewhat - use wind resistance as a positive - a supertanker and a dinghy, both with a sail the same size , so air and water resistance a factor but its all the same..who's gonna win the race?

This dude has an aeronautical engineering degree yet still he can't see it.. and his friend is a non-current skydiver, and he can't see it either.

I'm gonna get real and make the bet something that might actually be paid, £100, thats 5 more jumps for me :)
Thanks all again.
