If two objects have the same size, then they have roughly the same air friction (if not account for variation in surface smoothness). If one object is heavier, then the same friction will present a lesser share of influence on its movement.ashkor87 wrote: ↑Thu Aug 29, 2024 12:05 am
Newton's first law works as you claim in a vacuum. When you factor in friction, it is a different thing.
Accelerating a lighter object indeed takes less energy than a heavier object. But, if you accelerate a heavier object to the same speed, the kinetic energy of the heavier object will be more.
Imagine an extreme. A tennis ball and a cannonball of the same dimensions. IF they start at the same speed, the cannon ball will fly longer because it cuts through the air easier.
I think.
Air friction is a second order effect, quite minor

You guys are too experienced NOT to have played with a fluffy ball. You can tell how air drag affects a ball clearly then.

@scambers73
Annual reminder that grounds pass tickets at the
@usopen (bought through the website) are disproportionately expensive. Thursday: $160, Friday $224, Saturday $228: At @AustralianOpen they start at A$29 ($20), @Wimbledon = max £30 ($40) and it's about the same at @rolandgarros
At the @AustralianOpen you can get a 1-week ground pass for something like AUD $130

Re: ATP WTA GS US Open 8/26 - 9/8 2024
I watched her practice yesterday.. it was interesting because instead of (in addition to?) the physio, she has a "mental, movement and mobility coach." I didn't know this as I don't follow players' social media, generally. So I was surprised to see three big dudes and a small woman out with her at the practice court. It was a hitting partner, a "performance coach" - he was leading the hitting practice basically, and then Fissette was kind of hovering around and was chatting to this woman who was taking notes and sometimes talking to Osaka (she also picked up some balls.. takes a village). I looked her up (Simone Elliott) and her background is in dance. Thought it was an interesting approach.

Putting Shelton-Tiafoe in the day session is a pretty wild choice by the #USOpen for tomorrow’s schedule.

Looking at the OoP for singles only they had no choice. Djokovic doesn't play day matches and there is no way they were putting two women's matches on Ashe.

A LOT of folks are gonna be pissed off that they aren't putting Ben and Frances as the night match. AND, Novak should be willing to play whenever- within reason, of course.

I agree and they are already pissed about it. I agree that Ben and Frances should be the night match but believe it or not I think this is the first time Sabalenka has played on Ashe so far.nelslus wrote: ↑Thu Aug 29, 2024 9:09 pmA LOT of folks are gonna be pissed off that they aren't putting Ben and Frances as the night match.

AFAIK* Djokovic never plays anywhere except the Center Court of a tournament. Again, I could be wrong about that.

I absolutely love the day kit. The night kit is pedestrian.

This is why so many buy grounds passes if they're attending the first week. It's also why the situation around prices of grounds passes is infuriating.Jon Wertheim @jon_wertheim
So many surprising/compelling/tight matches through grounds of @usopen
on this gorgeous day..and in Ashe? Sinner wins 6-4, 6-0, 6-2 and Swiatek up 6-0, 5-1....A phrase you don't often hear: pity the folks in the suites. #USOpen2024

Re: ATP WTA GS US Open 8/26 - 9/8 2024
I don't think I tracked that Djokovic never played day matches anymore. Of course he should be on center court, but it's ridiculous that they allow him to dictate the night matches. The funny thing is, I remember there were a couple of years way back when (2011 was one of them) when he requested to play on the old Armstrong stadium for his round of 16 matches. That was when he was in full-on trying to ingratiate himself with the crowd mode...I always figured someone on his PR team told him that's where the real tennis fans were...ti-amie wrote: ↑Thu Aug 29, 2024 9:13 pmI agree and they are already pissed about it.

It looks like you can bring food! I do remember showing up sometime between 2008 and 2019 and food, a drink, and sprayable sunblock were confiscated before entering the grounds. (I used to go every year starting in 1993 through 2001... never had a problem then.) We brought empty water bottles with us this time - not big ones, they probably held 16 oz. Motobass and I were in in parallel lines to enter during the quallies and his line was moving so slowly. The person in front of him was having a problem with their stuff, so he got in my line - the inspector just passed the bag through without looking. (We brought only one non-backpack cloth bag that was close to meeting the size rules.)mmmm8 wrote: ↑Mon Aug 26, 2024 3:58 pmIrena2 wrote: ↑Mon Aug 26, 2024 2:53 pm Motobass and I bit the bullet and got two seats tonight in Louis Armstrong, not together, but in consecutive rows. Bought at the box office to avoid extra fees, but still over $300 for the night session. Hoping the day matches run long to tuck in some time before the first match starts. We, too, miss the old days of the Quallies when it was about the matches. We did get to see a day and a half of good tennis, and we probably could have gotten away with bringing food because our bag checker was chill, but other people weren't so lucky.
I am surprised tickets are still available at the box office!
I've never had an issue bringing food, just liquids.Is this new? I guess I'll find out this week
We felt lucky to get a couple of tickets at the box office to the night match the day before, but there were only a handful of tickets left in Armstrong, no grounds passes, no AA day or night, no Grandstand or LA during the day either. Next year we will plan it out well in advance, fingers crossed!

ABC, owner of ESPN, is broadcasting the US Open on the network on Sunday at 3pm. That will almost certainly be the men's match on Arthur Ashe, and it will feature an American vs probably Djokovic. So the Americans are scheduled for a day match tomorrow because they're going to play a day match on Sunday, and the winner won't have to change their schedule.
