physics.js attractors, zero gravity and slowing down velocity

I've been experimenting with attractors in physics.js, rigging up a simple object in zero gravity, with an attractor at a point. This creates a great little 'gravity well' as can be seen here. Where the simple square vector attracts towards a point,…

Android accelerometer sensor values

I'm playing with accelerometer sensor on Android Wear. When I'm reading the values in listener it gives me an array of for example [-19,594337 -19,594337 19,594337]. I mean, really? 19 m/s^2 in all dimensions? Bet Mike Tyson can't do better. Can…

Acceleration and Velocity from X,Y Position Stream C++

I have a stream of (x,y) data that I want to determine velocity and acceleration from. The data is pretty typical and can be thought to represent say a car driving around. A new data point comes every 2ms and I would prefer to not accumulate/store…
