Variation in throwing a ball

I might as well make a new tag called “basketball throws” because I can’t stop with the analysis of these crazy basketball shots. Watch – in the end someone is going to post a video about how all these were faked (and I have said there is no clear evidence they are fake). Oh, if…

Somewhere on the internet, I came across this Cracked.com article on movie myths about guns. The article wasn’t too bad, but I really liked this video they included from Arnold’s movie Commando. The myth for this particular clip was that guns never run out of ammo in the movies. Right away, I thought: I wonder…

Do Bikers Cheat?

Well, maybe that isn’t the best title. You see, there is this video going around saying that it is possible that a professional bike racer was cheating by putting a hidden motor in his bike. I am not really going to talk about the cheating aspect (my gut feeling says that it would be too…

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…

The speed of exploding Galacticus

This is really random, but quick. I was channel surfing and saw the end of the movie: Fantastic 4 – Rise of the Silver Surfer. SPOILER: At the end someone really big explodes in space. There, that wasn’t too much of a spoiler, was it? (unless you read the title) I know I am a…

Another Video Analysis Tutorial

I made this screen cast for my algebra-based lab. Maybe you will find it useful also. This is a tutorial using Tracker Video Analysis (an awesome free program as I have said many times). In this tutorial I analyze a moving cart that shoots a ball up and lands back in the moving cart (called…

I recently posted a tutorial on using Logger Pro for video analysis. Why did I use Logger Pro? Why not Tracker Video? Here is a quick comparison of the two. Logger Pro In the previous tutorial, I used Logger Pro. The primary reason was that the tutorial was for a lab course. The students were…
