Buttons

1. The start button sets all the values to default and enters you into the simulation environment. It only appears once, when you first run the code. To get back to the start button/start screen, you must close the program and restart it.

2. The restart button sets all the values to default and re-enters you into the simulation. All previous data that has been collected is deleted. This button appears on the DATA and SIMULATOR screens.

3. The two-way button with options elastic and inelastic allow you to toggle between the two types of collisions. By default, the inelastic collision button is selected when you press the start or restart buttons. The currently selected button is shaded in gray with white text. If you want to select an option, click the button and it will turn gray.

4. The data button displays the DATA screen of the program. Press this button once the simulation has finished to view the graphs of the velocity, momentum, and kinetic energy of each block.

5. The start simulation button begins the simulation and tells the blocks to begin moving.
