# Another example of a dangerous jump

Check this out. So, the guy jumps from 150 feet into some cardboard boxes. Why are the boxes important? You want something that can stop you in the largest distance to make your acceleration the smallest. Here is my Dangerous Jumping Calculator. Basically, you put in how high you will jump from and how much…

# Physics Tips for Media

You probably already know how I feel about the “media” and their physics explanations (see attacks). Let me summarize the problem. There are a whole bunch of cool shows on tv that deal with sciency stuff – that is good. These shows then try to teach some science along with their demos and explosions and…

# Big spaceships with even bigger thrusters

If you have been on the internet, you surely have seen this website showing the sizes of different starships. Way cool. Here is a small sample – but it doesn’t do the site justice. You really need to go browse around. Of course, I can’t let something like this just go. One of the things…

# 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…

# Faster than terminal velocity

I had so much fun creating graphs for the Red Bull Stratos Space Jump calculation, that I figured I should make some more. Can you fall faster than terminal velocity? That is the question. Air Resistance Air resistance is a force exerted on an object as it moves through some stuff – air in this…

# Ski jump landing and acceleration

My last Olympics post may have been a little complicated. I am going to try to make this one a little easier. In this post, I want to look at the landing portion of a ski jump. This could apply to THE ski jump, but there are some things in that even that make it…

# Acceleration of Google’s Newton’s Apple

This is great. Many people have already reported google’s apple-dropping homepage in honor Newton’s birthday. In case it disappears, here is a screen shot. So, I got this awesome note from Dale Basler. He said that his class had analyzed this falling apple animation. What a very Dot Physics-y idea (check out his analysis). He…

# RP 2: The Physics of Fantastic Contraption

One of my students showed me this game, Fantastic Contraption. The basic idea is to use a couple of different “machine” parts to build something that will move an object into a target area. Not a bad game. But what do I do when I look at a game? I think – hey! I wonder…

# Fight Science = Bad Science

Fight Science is an entertaining show. Great graphics. The basic idea is to look at the science in different fighting styles. They had a clip-style commercial on it during a MythBusters episode I was watching. And from that, I can say that the kicking looked cool, but the science needs some work. The Setup The…

# Dangerous Jumping Calculator

Maybe this could fall under my “physics of parkour”. It could also apply to the MythBusters “dumpster diving” episode. In both of these cases, the question is: how far can you jump off of something and not severely hurt yourself. They do this a lot in parkour. Here are some examples: There are a ton…
