Bring the 2nd Law of Thermodynamics to life.
Slides through a special slot in the Rotary Motion Sensor and allows you to measure short linear distances.
Allows students to conduct experiments to measure the speed of light. Reflect a laser off a movable mirror into a light receiver to measure phase differences.
Determines the current through the sensor by measuring the voltage across the internal resistor.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Allows students to measure angular velocity, acceleration, centripetal forces, and other full range of motion experiments.
