same rate as what? A free falling person who just jumped off the cliff with no wings? He's descending at a substantially slower rate than someone free falling because he's converting so much of his downward energy into forward energy via wings + wind resistance. If he wasn't slowing his rate of descent so much, the only forward energy he would have had was what he got in his initial leg jump, which was about 8 feet. He landed what looks like several thousand feet away from where he jumped.

No, he's falling at the same rate as if he jumped with the suit and made no attempt at forward motion.

This is the same as the old "Fire a bullet out of a gun the same time you drop one" puzzler.

No, because the bullet has lots and lots and lots of forward energy to begin with. Not the same at all. His only initial forward energy is from his legs. And unless he's some super freak of nature, he couldn't have jumped outwards several thousands of feet.

Think about it, the whole reason the bullet falls at the same rate regardless of being shot or dropped is because the downward energy is the same, but the shot bullet has a lot of added forward energy via the gun.

Energy isn't free. Unless you're claiming he was shot from an invisible canon, that energy came from somewhere that hurled him forwards thousands of feet. It came from converting his downward potential energy into forward energy.

It's like you don't fall at the same rate going down a slide as you do if you jumped off the top, even if the slide was purely frictionless, because the slide is converting some of the downward acceleration into forward acceleration.

Um,.......... wrong!

They will hit the ground at the same time.

And the same principle applies here. If he jumps, then falls perfectly straight down (with his suit deployed just like he does in the video), he will descend at the same rate as he is in the video. Heck, even some old geezer by the name of Isaac Newton knew this.

Holy! That would be so much fun, probably would of pooped myself when I came that close to the ground.

That was a little insane, right? WOW!

He hit the rocks earlier this year:

That had to hurt...

Yea... Major OUCH! I can see where you would want to push the limits.. but too close is too close....

yes, I'm aware that a bullet hits the ground at the same time regardless of if dropped or shot. That's because the forward energy of the bullet is all provided at the initial blast. The bullet doesn't have to get any additional energy to go forward.

The jumper on the other hand is a totally different story. He has almost no forward energy to start with. Where do you propose that this energy that propelled him THOUSANDS OF FEET FORWARD is coming from? THink about it his way:

You're saying that he dropped at the same speed downwards and would hit the ground at the same time as if he had just jumped straight off and not gone thousands of feet forward. Now draw a triangle. He covered a ton more distance. If he covered the hypotenuse of that triangle in the same amount of time as the downward leg would have taken, he obviously would have had to go MUCH faster in the diagonal vector. Meaning he somehow would have gotten free energy. Free energy doesn't exist. If anything he was losing some energy due to increased friction, due to increased wind resistance from the suit.

Isaac newton's experiments were about dropping items of different weight both straight down, which again was COMPLETELY different.

Can you also not be so condescending with your "um, ...... wrong?"

You can't just glide forward thousands of feet with no impetus of energy whatsoever. Are you claiming his legs propelled him thousands of feet forward? The only way he could have gotten that energy was by using the wings to convert potential energy via gravity, through wind resistance and his 'wings' into forward energy.

It's essentially the same principle as how a spoiler works. It's well known that in aerodynamics, a spoiler works by taking the wind resistance and turning into downward force on teh vehicle. The cost is a loss of forward acceleration though. A car can go faster straight forward without a spoiler. The spoiler converts energy from one vector to another. Same principle here. His wings are converting downward acceleration force into forward acceleration force via wind resistance.

try this:

get on a tall building and lightly toss a paper plane and a balled up piece of paper at the same time. See which hits the ground first.

 

[Trever1t]

not quite a fair comparison, try a rock with paper wings and one without

Gravity is pulling you down all the time non stop. To slow it you need to start using energy in the opposite direction. I don't think you can take energy from gravity to help you go up. You are going slower because you are gaining lift with the suits. Just not very well like a plane does lol. That's my 2 cents and I'm not an expert just a guess lol.

ha, those suits are made of kevlar I believe.

I'm confused, are you saying that he'll hit the ground at the same time with or without his suit?

you don't actually have to use lift, you just need any wind resistance, directed properly.

It's like a parachute, but the parachute only coverts downward force into upward force (though there is obviously more downward force than upward force, the upward force does cause the rate of acceleration downward to slow drastically, and hit equilibrium of no continued acceleration fairly quickly, and then drifting down at a constant speed). These suits are designed to convert downward force into forward force instead, but they still 'cost' downward acceleration, meaning the rate of drop is slowed from someone who just jumped straight off with no suit and didn't propel himself forward.

There was a twist to what sparky said though, he said "jump straight down with his suit deployed"

If he jumped straight down with his suit deployed a few things could happen, which would all be vastly different:

1) If he just jumped down feet first, he'd hit the ground WAY faster, even if his suit was opened. Even though the suit was opened, it wouldn't be catching much wind resistance, and in fact would probably serve to make him more aerodynamic.

2) If he jumped at the same angle, his "went straight down" becomes impossible. The jumper wasn't making any 'effort' to go forward, this was completely determined by how he was catching the wind resistance, which is determined by the angle of his body in relation to the ground (ie gravitational pull). In this case, yes he'd fall at the same rate, but he'd, again, travel thousands of feet forward too.

3) If he managed to be completely flat in his descent and descended straight down, he'd actually descend slower than when he jumped down in the video, as he'd be converting all the wind resistance into upward energy. (ie a parachute effect)

So "jumped straight down with his suit deployed" has no meaning without specifying the angle of his suit in relation to the force of gravity. The only way he'd descend at the same rate with the suit deployed would be if he jumped at the same angle, but in that case it would be literally impossible for him to go straight down. There isn't any way, with the suit deployed fully, for him to both jump completely straight down, and go downward at the same rate. It would either be way slower (suit perfectly horizontal and only providing upward force) or way faster (suit perfectly vertical, thus providing little resistance to the wind at all).
