LOL, this thread has become a middle school science class. Heavier objects do not fall faster, only aerodynamics could effect rate of descent.

This thread was worthless to begin with though since a 555 HP X5 will smoke 99% of things on the road.

I don't think it's 'worthless' if someone can listen and start designing cars that feel fast. Let's take it to the extreme (science fiction)

The episode of Star Trek the Next Generation where Scotty was locked in a transporter for 60 years (I think) and was beamed into the 24th century. He said he could feel the speed of the ship (1701, no bluddy A, B, C or D) through the deckplates. The newest Enterprise had perfect inertial dampers and no sense of warp speed. The march of technology!

Which do we want, speed. The feeling of speed, or both?

I know that in my youth it was more important to be first. Now, not so much. I could care less if the car does 0-60 in under 4 seconds, but if it feels good to drive (like a diesel) I like driving it more.

You do have a point...

I think I remember a quote from Rick Mears. Someone asked him what it is like to go 200 miles per hour. He stated it is like drive 60 in a ford Pinto.
Not sure about the exact quote but you get the point.

99% of the time yes, unless the density of the air is enough to give bouyancy to the lighter object... like a light annd fluffy bubble.

Just think of a basketball being dropped next to a same sized ball made with walls as thin as tissue paper... Or a baloon filled with water next to one filled to the same size with mainly air and only an ounce of water.

thanks weasel .
I put my wings to roost years ago.
still trying to get a grip on how to explain this .
too much of the skygod banter in my head to actually remember the classroom stuff .
as for scotty from star trek , people who spend months on a hospital bed have a hard time adjusting to sitting upright and a real scary time if sat in a wheelchair the moment they sense motion .they become hypersensitive to motion .
I gotta find the formula to elaborate on W=mg , can`t remember all the air resistance stuff .
by the way , did you hear the one about the constipated mathematician , he worked it out with his pencil .
I gotta go get some sleep now , I feel as though I am on the GCS(Glasgow Coma Scale )
this was invented at Glasgow University and is used Internationally to diagnose the state of conciousness , probably discovered as a result of the Glasgow kiss ( a headbutt to the face ).
see y`all .

Hmmm. Invent a pill to induce that 'been in a hopital bed for months' feeling when driving a car.

Driving a Mazda Miata around a track would be more thrilling than driving a V6 Porsche Panamera. Fer sure, totally!

OK Amacman, I can feel the pain in your synapses as you try to think back to high school physics, so I will lend you a helping hand.

FORGET the mass...and the weight...M and W don't apply to the velocity in TT Bear's "X falling off a cliff" example. The only thing that matters here is the acceleration of gravity (g): 9.8 meters/second^2. This number applies to all objects regardless of their mass. The 2 variables which CAN and do lead to different falling rates is cross-sectional area and coefficient of drag (Cd). Hence, the wonder of PARACHUTES!

However: in TT Bear's example the difference in Cd between a free-falling 4.6is and an X5M is basically negligible. Therefore, the 2 vehicles would finish in a dead heat even if the 4.6is had 3 fat dudes in it.

I think the reason your brain keeps coming back to mass (m) is this: even though the 2 beautiful X5s will hit the ground AT THE SAME TIME, the 4.6is with the 3 fat guys will impact with much higher kinetic energy: KE=1/2*mv^2 Therefore the sunbather at the bottom of the cliff who gets hit with the 4.6is will end up more "compressed" and flatter than the sunbather who gets hit with TT Bear's X5M.

good stuff
my brain is mince
everything you say was already dancing around my head incoherently , now it makes more sense .
thinking back to how four of us could freefall in formation passing a small ball between us , it all makes sense .
