Pulleys Program:

This program simulates the mechanic movement of two pulleys connected with a spring(between them) and with two other springs (to the walls):

This program is supposed to simulate the real mechanic movement (not in real time) of two pulleys connected between the with a spring and also connected to the walls with two other springs. The user can set up all the variables which determine the movement. This program also draws the kinetic and potential energies graphics, and you can clearly difference each pulley energy since each graphic is drawn using a specific colour. Moreover, you can set the two normal modes of the system (which are demostrated in the .pdf file), and you can slow down or accelerate the motion speed (or even pause the movemeny), so you can study perfectly the mechanic movement.

Lagrange Equation Program: Three masses and three springs

This application simulates a physical system that consists on three masses assembled to three circular wharves. The masses are supposed to not to be affected by the force of gravity and they can only move in one direction (constant radius but changeable angle). The first mass (mA) is assembled to the first spring (kA), and to the second spring (kB). This one is connected to the  second mass (mB) which is assemble to the third spring (kC) that connects with the third mass (mC). The application is focused on the action between the springs and the masses so the collisions among the three masses are not considered.

Pendulums Program:

This program simulates the mechanic movement of two pendulums connected with a spring:

In this program the user can set up all the variables needed to determine the pendulums movement. The program is supposed (not in real time, though) to show the real movements two pendulums should have if we "copy" the initial conditions, and it draws the potential and kinetic energies. Moreover, the user can accelerate and slow down the speed so he/she can see specific interactions between both pendulums, as well as pause them or stablish the two "normal modes" (in which the pendulums have the same movement, or the reverse one).
