Does anybody know what this Liverpool player is drinking from? They only showed a very brief shot of this during an injury pause after this player scored the first goal of the match.

In this video, the history of championship javelin throws is discussed, as well as how the sports authorities kept changing their design to prevent distant throws and subsequently rewriting sports history.

I am organizing the darts tourney for about the fifth straight year. We play once a week. This year there are about 40 players. (10 teams of 40 players each, because eight teams of 5 players each makes for a slow game). We want to have fair teams, and I've been pretty bad at judging skill...

Let's say you are riding a bike very fast, and then you sharply turn into a slide (where the bike is sliding perfectly sideways). I'm trying to calculate the angle that the bike would be leaning at, but I'm having trouble creating the free body diagram. Right now I have the normal force and...

Hello. I am working on a physics project for a simulation title and have stumbled upon on an interesting challenge. Below is the example from wind tunnel data of a Dodge Viper GTS sports car. Wheelbase: 2,44m Lift front axle: 54kg Negative lift rear axle: 26kg Can somebody please explain to...

I am ~180lbs and have been lifting weights for about 12 years straight. I have also been running 3-4 times per week for the last 8 ish years. I have recently gotten into cycling, and noticed at the gym on the Schwinn "spin" bike, I will have peaks of around 400-500 watts, but it's definitely...

Hello Physics Forums, I enjoy playing pool, my knowledge of physics is almost nonexistent, so I apologize in advance for my ignorance. In a nutshell, I would like to understand how the hardness of a pool tip effects energy transfer in that brief moment of impact when a pool cue tip hits the...

Hello, When I watched live matches of football (soccer) leagues and MotoGP, live commentators often speak British accent. If I want to be live sport commentators, will mastering British accent (RP) be helpful, assuming that many commentators speak RP and I have taken ESL course? Cheers, Bagas

In a school 315 girls play at least one sport. 100 play a fall sport, 150 play a winter sport, and 200 play a spring sport. If 75 girls play exactly 2 sports, how many play three?

Nerds are usually considered bad in sports. But in some sports, they seem to be in fact better than average population. For instance, it seems to me that they like mountaineering and climbing more than average population. What are your experiences?

What are the differences between ring and field? It's for an article that I write.

Hi there, TL/DR - I have a community college job with a sufficient salary. Should I be happy with that + freetime or should I try to get a job which really uses my PhD? If I go with happy freetime option, are any of the projects I propose interesting AND feasible? If I am too lazy to follow...

Hi, I am interested to find out the answer to whether high tension or low tension strings on badminton/squash rackets give more power/force. There are so many conflicting sources on the internet I wanted to see if it can be answered in a concrete way by physics. So, some sources are saying that...

Interesting little development in [sports] media: Fox Sports, which was my go-to for sports reporting has fired all 20 of its writers (seems like a really small number...) to focus entirely on video. I noticed this a week ago when I went looking for commentary on the NBA draft (Philly had a...

Hello, I want to do a masters degree in sports medicine. please suggest me some colleges like http://www.scuhs.edu/academics/atce/residencies/chiropractic-sports-medicine/ Any suggestions would be greatly appreciated.

I have a decent background in physics, but something that has always confused me is how to think about how the tension of the string in a tennis racquet affects how the ball leaves the strings. For example, the traditional lore in tennis is that tauter strings will give more control, whereas...

i've been wearing a light impact sports bra in place of a normal bra for the past few months, since they are comfortable: https://www.amazon.com/dp/B004NPTV2G/?tag=pfamazon01-20 But I've noticed that my breasts when bare have been shifting to the sides (i'm thinking that it's because the bra...

I am a writer trying to calculate possible outcomes in sports - specifically, relating to the NHL: There are 30 teams in the league, my questions are: All else being equal (ie. random draw), what are the chances of all 7 Canadian NHL franchises finishing in the last fourteen -meaning they're...

Okay so here is my idea, not really sure how well (if at all) it would work but I am wondering if it would be possible (assuming battery technology is good enough) to ionise air in front of a formula 1 car (or plane or whatever) giving it a charge (like the way lightning works) , then creating...

Hey I'm a grade 9 student and I'm very interested in doing something with sports medicine. I don't know what I want to do for sure yet but I'm thinking about becoming a physiotherapist. I not a very high grade scorer my grades are at a average but some are a bit over. What grade percent would I...

Hey all, This seems like a better venue than almost any to make this inquiry. I adore weightlifting and barbell sport, and find anatomy and the applied use of ergonomics very interesting as a rather serious recreational musician as well. I love to discover the "why" behind certain postures...

Watching this video swirled a lot of thoughts and emotions in my mind. After the UNC scandal, it all makes more sense. In my mind we are completely selling these kids out. The video brags about the colleges some kids get recruited for, yet it doesn't talk about how many get drafted. So the kids...

Hello all, If you have been watching the olympic games lately you could have seen that in the past week it has occurred twice that an athlete won (and another lost) a gold medal by a time difference of a few 1000th of a second. Both occurrences where in speed skating (i.e. the 500m and 1500m...

This is a spoiler for all Artificial gravity space crafts. If somebody thinks that he can do whatever he can on earth, on the Space Craft, then here is bad news: No football, no soccer, no cricket, no birds can exist on the craft without confusion. :confused: Here is why: A projectile...

i have read an article a long time ago about left handed people being faster than right handed people in sports. it was because the impulses received from sensory neurons end up in the one hemisphere in the brain and has to pass to the other one then a message is sent to motor neurons in...
