For use with Lascells timers. The subject presses the START button and after a short random delay the light comes on. The subject has to press the button as quickly as they can in response. The timer records the interval between the light coming on and the button being pressed. No power supply required.
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
This system is ideal for hands-on experimentation with basic circuits and includes more components than the Basic Set, as well as sensors. It is a component of the Essential Physics program.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
Determines the current through the sensor by measuring the voltage across the internal resistor.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
Allows students to mount Rotary Motion Sensors to the Rotating Platform or Gyroscope.
