More basketball analysis

Reader Jorge has also looked at these amazing basketball shots. (here is my last basketball analysis) Jorge claims that at least one shot seems fake. He is referring to the following video (at around the 2:20 mark). ARRGH Ok, new plan. For some dumb reason, youtube won’t let me embed this video. Well, here is…

Basketball shot – real or fake?

I have seen several videos similar to this. Real? Fake? How many tries did this take? Let the analysis begin. Before I do any analysis, let me state that I think this is not fake. I do not know that for sure, just my first guess. How would I tell if it is real or…

I nominate Frank

Frank Noschese is a physics teacher and a blogger (and frequent commenter on Dot Physics). And I nominate Frank as the new librarian of videos that can be analyzed for realness or fakeness. Or, as Frank calls them Win-Fail Physics. Note that I sort of changed his theme a little – sorry Frank. Win-Fail physics…

Mercedes Roll

Here is a commercial for some Mercedes car. The first part is quite boring, but check out the stunt at around 2:00 minutes into the video. I haven’t bothered to check if this is officially fake or not. Instead, I will do what I do – see if this is even feasible. The common question…

What is Arnold made of?

Of course I am talking about Arnold Schwarzenegger. After looking at how many bullets he carries in Commando, I remembered this scene (also from Commando) (warning: maybe some not great language and some killing. You have been warned) If you don’t want to watch that clip, here is a shot (sorry for the quality). Clearly…

Sport Science FTW!

Normally, it isn’t really news when a show doesn’t do anything wrong. I am making an exception for ESPN’s Sport Science. Here is part 2 of Sport Science trying to reproduce Kobe Bryant’s “jumping over a car” stunt. And here is part 1 (although part 2 is the only interesting part). See. I can get…

Apolo Ohno’s Slime Jump

Here is a quick Apolo Ohno quiz. Which one of these pictures is fake? If you picked picture B – you are probably correct. That is a picture of “Apolo” being catapulted into a pool of slime at the Nickelodeon awards show (click on the link to see the video – I don’t think I…

More ESPN Sport Science Goodness

Let me be clear. I am not really an attacker. If someone wrote a report about ski jumping or something and misused the word “momentum”, no big deal. However, if you have a show that claims to be about SCIENCE and you are obviously putting a lot of money into this show AND a whole…

Hat tip to Frank for sending me a link to this video: If you have never done a demo like this (without the motorcycle), you should. It really isn’t too difficult. Here is a video of my version: Inertial demo from Rhett Allain on Vimeo. So, the question is: is the motorcycle thing real or…

Sport Science, Pulling and Friction

Forgive me for all the posts on ESPN’s Sport Science (example: Pulling and Power). I can’t help myself. In the short episode recently, Sport Science compared a football player pulling a sled with huge tires on it to a truck pulling stuff. I think their goal was to compare the power per kg from for…
