Tail-Drop Analysis

I don’t know why they call it a tail drop. Here is a video: The link I clicked that brought me to this video said the equivalent of “OMG!” That is not what I thought, really I am not sure what is so impressive (except that he didn’t fall off the skateboard). If the original…

And there’s parliament. Ok – sorry, I had to make a “Tom (Swans on Tea)” title for this one. Tom, forgive me. Here are two great circular motion videos. First, this one is from Dale Basler. He made himself a fine little floater-type accelerometer. Better than just make it, he made a video of the…

I am excited. This Wednesday, the MythBusters are doing the giant water slide jump. Maybe you are new to the internet and you haven’t seen this video. Here it is: And since it is as old as the hills, of course I have already analyzed it – actually twice. First, the video is fake –…

Oil Spill Estimation

I was going to just leave the oil spill in the gulf topic alone. Not because it isn’t important, obviously it is. Rather, I wasn’t going to do anything because I didn’t really have anything to add to the topic. After a couple of readers requested it, I think I do have something to add.…

I was going to make this as a video tutorial, but it just didn’t work out right. So, here it is in blog post form. How do you deal with a video that zoom and pans at the same time? You could keep on adjusting the coordinate axis AND adjust the scale for each frame…

Some People Running

This video seems like it is getting popular, but maybe that is because it is so awesome. Maybe it is just me, but I find this video very visually satisfying. I love the way they compare the different runners. Anyway, there is some physics here. Commenter Ben sent me the link to this video (thanks!)…

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…
