Who's working harder for their million? Bekele. Isinbaeva, or Richards?

Bekele

13:00, 13:04, 12:56, 7:28, 12:52(WL)

Richards

49.57, 49.23, 49.46, 49.34, 48.94(WL)

Isinbaeva

4.83m, 4.71m, 4.85m, 4.65m, 5.06m(WR)

I say Bekele, Richards, then Isinbaeva.

You guys are all a bunch of clowns. Seriously, go back to intro mechanics, you all fail.

The guy who said it was a dot product has the most general definition of work, so he wins there.

However, remedial poster is incorrect because we are talking about walking. You must have a force exerted on your feet by the ground with each step to walk without slipping, thus there is work being done on the person-rock system. The example he means to use here is riding a skateboard or something while carrying a rock at a constant height above the ground. Once the skateboard is moving, no work is being done on the rock in the HORIZONTAL direction. This distinction is important because as pennywise de clown pointed out, both force and position are VECTORS, which means the direction matters.

In fact, this distinction matters so much that the skateboard is still wrong if you are talking about the total work done on and by the person-rock system. Think about it for a minute. If you're not doing any work on the rock while riding the skateboard, why do your arms get tired? It's because the muscle fibers in your arms are DOING WORK in the VERTICAL direction.

It's important to point our here that your arms are not doing any work directly on the rock itself. That work only counts if you include the person holding the rock in your system. It's also important to realize that the example physics teachers always use to emphasize the directional nature of work (holding a rock steady while walking sideways) sucks because it leads to this kind of confusion.

In case you are wondering, this is what happens when the recession puts a high school physics teacher out of work.

Isibayeva and Bekele generally coast through some of their competitions as they are absolutely dominant. Yes Bekele can toy with his competition and there are only a 2other very good vaulters. Richards has to work hard every race.

Isinbayeva. Running is easy compared to the preparation she has to do for each vault.

idiot...who is going to beat isinbayeva? Bekele's competition is much better than hers and he has to deal with the fatigue that comes from racing a bunch of 5ks (and 10ks) with very little rest while the competition gets as much rest as they want-they can skip a race while he cannot. you f***

You don't really know much about Isinbayeva do you?

Richards hasn't been absolutely dominant at 400m this year? I don't think she's lost a single 400m race this year. How can you say Bekele and Isinbaeva "coast through" some of their competition because they are dominant, but negate Richards' dominance for the sake of proving she doesn't "coast through"? Virtually no other woman has been able to run sub-50 this whole season, so if she just focuses on running sub-50 but not going as hard as she can it's practically a lock that she wins every race. It's like saying if Bekele went out to run sub-12:50 every race there are only maybe a couple runners who could go with him, so he knows it would be a lock or that most of the competition would not be able to compete with that. And just because Richards wins all her races doesn't mean she's sprinting through the finish line. Many 400m runners who have a substantial lead coast(or ease up) the last 10-20 meters. I think you're under the impression that because she is sprinting and exerting more force with each stride that she is 'working harder'.

I believe she lost one very early season race... but now, she has the most sub 50 clockings of any woman EVER.

she is a butterface

I'd give it to Isinbayeva, not only does she have to run, vault, fall, master apparatus, etc. she also does it looking damn good.

Much, much tougher than getting ugly over 400/5,000 meters.

Not a bad summer. Tiring I'd imagine, but profitable($333,333+ [in euros?]).

I think these are all the races Bekele ran this year. He might've ran some earlier ones, maybe before the summer began, but even without earlier races in the year, that's still an impressive string of competitions, in which all of them he placed first. even the 5000m heat at the world champs.

to compare, here's what tegenkamp's outdoor season looked like:

13:22 (cardinal invite/peton jordan) 2nd?

7:37 (pre classic) 4th

13:20 (usatf champs) 1st

13:07 (european meet) 2nd

13:20 (wc 5k heat) 2nd

13:20 (wc final) 8th

12:58 (brussels) 7th

whoever says tegenkamp doesn't race enough, i don't believe that. maybe that's true during his off-season training, but that looks like a substantial number of meets for may-sept. that's at least one meet every 4 weeks. and he may race more, who knows?

running 13:20 is nothing for tegenkamp now. he did it 3/4 times this summer, and 3 of those races were for qualification or more tactical race, and not just for himself (wc's)

i'd still be nice to see tegenkamp bust out a 3k or 1500m before the summer is over. the 3k AR should be next to be assaulted, and the 10k as well.

to the memory of bk's 12:58
