Oh, I hear you are going to start a scuba diving class. Or maybe you headed off for a 2 month adventure where you do a WHOLE bunch of scuba diving including scuba certification all the way through Dive Master. Great. I’m sure you will have fun. I’m going to…

With normal (plain vanilla) projectile motion, there’s only one force acting on an object — the downward pulling gravitational force. If the object is near the surface of the Earth, this force is constant. With a constant force, projectile motion is fairly (but not completely) straight forward. But what about…

Who cares about pile drivers — especially on different planets? Well, apparently Zach Weinersmith does. This seems like a great physics question — so I’m going to find a solution. But first, let’s take a moment to recognize that I actually had a picture of a pile driver. Yes…

I was rather disappointed when I did an internet search for “speed to low earth orbit” and didn’t get an answer right away. Fine, let’s fix that. I’m going to go through all the calculations for orbits and stuff. The answers will be right here at the top with the…

I don’t really do much with horse races, but you have to admit that this is like the Atlanta Falcons being up 28–3 over the New England Patriots — and then the Patriots win. Sorry if you are Falcons fan. I know that one hurts. OK, so here’s the deal…

Let’s be honest — the world is made of springs. OK, maybe they aren’t literally springs but they are approximately springs. Yes, for small oscillations we can approximate stuff as a simple harmonic oscillator. The Physics Problem Suppose you have a mass (m) connected to a spring and the mass…

There’s a very good chance that you have at least plucked a guitar string. When you do that, you deform the string under tension with some initial state. After that, the “plucked” parts of the string interact with the other parts of the string — and you get a wave. …

You might not realize that they are important in physics — but you pretty much need both Stoke’s Theorem and the Divergence Theorem for vector stuff (like Maxwell’s Equations). However, they can be a little difficult to comprehend. I’m not going to derive these two equations, instead I am just…

You just never know when you might have to jump over a car that’s speeding straight towards you. Oh, and maybe that car is a McLaren sports car — you know, it could happen. Even more importantly, this could be part of a TV show called America’s Got Talent: Extreme. …
