With this application, you can monitor the motion of a mass-spring system in real time using your device's camera. The application automatically detects the position of the mass through image processing, displays the displacement-versus-time graph, and calculates the average oscillation period.

Instructions:

1. Suspend the mass from a spring so that it can oscillate freely.
2. If you are using a mobile device, place it on a stable support with the camera facing the mass-spring system.
3. If you are using a computer, position the mass-spring system in front of the webcam.
4. Position the mass in front of the camera and keep it oscillating slightly.
5. Click the Turn On button to enable the camera. The application will automatically capture the equilibrium position of the mass.
6. When the message Baseline captured. Pull the weight down, release it, and click Start. appears, follow those instructions.
7. If the green line is not close to the base of the mass-spring system, click the Restart button and repeat the procedure.
8. Click the Start button to begin data acquisition.

Buttons:

• Starts or pauses data acquisition.
• Turns the device camera on or off.
• Restarts the experiment and performs a new calibration.
• Downloads the experimental data, including time, displacement, and mass velocity.
