PhET: Masses and Springs: Basics
Hang masses from springs and discover how they stretch and oscillate. Compare two mass-spring systems, and experiment with spring constant. Transport the lab to different planets, slow down time, and observe the velocity and acceleration throughout the oscillation.
PhET: Density
Why do some materials like wood float in water, and others don’t? Interact with blocks of different materials, including a custom option by modifying their mass and volume, to explore the effect on the density and discover the conditions for sinking or floating in water. Play detective to determine the material of each block by comparing its density with the values in the table.
