Algodoo

This scene measures the frequency of the vibrating block and then calculates the mass from m = k/(2*pi*frequency)^2. Scripting is in the laser. The mass measurement is not affected by air buoyancy and the system will work in the absence of gravity. The system will measure mass from 0.1 to 1.0 kg.

Note: I made this then looked to see if anything like this existed. It did and it is called a inertial balance. I don't know why it would be called a balance. There is no balancing.
