Dot Physics

How does an accelerometer work? Really, an accelerometer measures force some way on a known mass. Let me show an extremely simple accelerometer – a mass on a spring.

Jennifer over at Cocktail Party Physics has a nice post about her trip to Disneyland. The one ride that would be fun to play with (in terms of physics) would be the tower of terror. Think of the cool things you could do with a video camera during that ride. It would [...]

Here is what is cool about Fantastic Contraption – it’s like a whole new world, a world ready for exploring. I am Newton, and I can see if this world follows the models that I propose.

In this post, I am going to explore the elastic nature of the “water-sticks”. If you have played [...]

In this post, I am going to talk about real and not real forces as well as the fake centrifugal force (if you don’t like the word “fake” you could replace that with “fictitious”)

First, an example: suppose you are in a car at rest and press the gas pedal all the way down causing the [...]
