At one point in the past, I was a teenager. Hard to believe, I know, but it's true. During that time, I thought about teenager things. In particular, I recall thinking about and wanting a super fast ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

gradient = \(\frac{change~in~y}{change~in~x} = \frac{change~in~speed}{change~in~time} = \) \( \frac{change~in~metres~per~second}{change~in~seconds}\) = metres per ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Most people see this video of the SpaceX Grasshopper on a test flight and point to the funny stampeding cows. Yes, that's funny but that's not what I see. Instead, I see a great video example that can ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

I know this stuff can get a little high-level and “strength-and-conditioning-nerdy,” but stick with me. My goal here is to ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

Linear motors are the most demanding part of point-to-point applications, requiring careful analysis to achieve accuracy and appropriate sizing. In high-throughput applications, standard triangular or ...
