Masses & Springs analyze masses and springs. A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring.

Sample Learning Goals
1. Explain the Conservation of Mechanical Energy concept using kinetic, elastic potential, and gravitational potential energy.
2. Use your understanding of how a spring scale works to determine the mass of an unknown object.
3. Find the value of g on Planet X.
