FísicaLab is an educational application to solve physics problems. The problems are set up by adding elements from the palette to a chalkboard and entering the data for each element. The elements are objects such as blocks, pulleys, motors, and forces. It can use the SI and English unit systems, scientific notation, and many conversion factors. The types of problems that can be solved are kinematics of particles (including circular motion), static analysis of particles and rigid bodies in 2D, dynamic analysis of particles in 2D (excluding the dynamics of circular motion), heat, calorimetry, ideal gas, and expansion. The static and dynamic problems are entered by constructing the free body diagrams of the objects.
GaussianBeam is a Gaussian optics simulator. It features table-top display of the optical setup. It computes the beam parameters. You can move optics with the mouse. Available optics: lenses, flat and curved interfaces, mirrors, dielectric slab, and generic ABCD. Magic waist function: given a target waist, GaussianBeam finds the suitable arrangement of lenses. Fit waist function: measure the beam radius or diameter to define the input beam. The ability to save and load configurations.
