The script lives here.

However, upcoming Drive migrations will change that.

Version 2 (last updated 1/19/2022)

// Start recording

  • Welcome to PhET Interactive Simulations!
  • In this video, I’ll show you the sound features in the simulation Gravity Force Lab.
  • In Gravity Force Lab, you can explore the relationships between mass, distance, and gravitational force.
  • To begin, move a sphere to change distance OR change the mass using the Mass Slider. I’ll start by changing the distance. //Grab m1 and move away and then toward m2, maxing out each side.
  • Do you hear the tone playing as the sphere moves closer to and farther from the other sphere? That tone represents the force as you make changes.
  • You’ll also hear a BUMP sound to let you know you’ve moved the sphere as far as you can or a WHOMP sound to let you know you’ve moved close to the other sphere.
  • Now, I’ll try changing the mass. //Drag m1 slider up and down.
  • The same tone plays! This tone increases and decreases in pitch with the magnitude of the gravitational force between sphere 1 and 2 as it changes. The higher the pitch? The higher the gravitational force!
  • This simulation has an Extra Sound feature, which we can turn on through the Audio tab in the Preferences menu. // Open Preferences Menu, click the Audio tab, and select Extra sounds. Close the menu (X)
  • Now, as we change the mass of sphere 1 or sphere 2, alongside the FORCE tone, you will hear a PERCUSSIVE TONE that changes pitch with the magnitude of the mass of the sphere you’re changing. //Slowly minimize and max out mass 2 slider.
  • The pitch gets deeper as you make the mass larger.
  • You can also measure the distance between the spheres with this ruler, //Pickup the ruler.
    • You’ll hear satisfying CLICKS as you line up the spheres. //Move as if you’re lining up the ruler to measure the distance. //Move ruler back to position, out of the way.
  • Explore different values for mass and distance to investigate their effect on the gravitational force!
  • Thanks for watching! If you want general tips on using the sim with your students, then check out the Video Primer!

This reads really nicely to me.
