Section outline

    • Through this video you can learn how to perform Free Fall with your smart phone by using phyphox app.

      Just have fun!

    • This experiment needs two smartphone, with phyphox app installed on each one. Do it with your classmate and try to estimate the velocity of sound.

    • using a solid ball, you can verifiy the energy transfer between potential and kinetic energy. Using phyphox application, you can measure the initial dropping height of the ball by using:

      • Sound Stopwatch: sequential measurements
      • Directly, choose (in)elastic collision experiment from the list
