Two masses hang from a light string over an ideal pulley. A motion sensor on the floor points up at m₁ and records its velocity and acceleration 20 times per second (up is positive). Start on Earth, then travel to a planet where g is unknown.
Drag a mass up or down to change it · Space releases · R resets · Scale: 1 m = — px

Use your measured acceleration and your two masses to calculate the gravitational acceleration on this planet.
