Allows students to measure angular velocity, acceleration, centripetal forces, and other full range of motion experiments.
See the Buying Guide for this item's required, recommended, and additional accessories.
Measure angle and angular velocity or measure distance and linear velocity using the rack or the pulley. This sensor is also bi-directional, indicating the direction of motion.
- Conservation of Angular Momentum
- Rotational Inertia of Disk and Ring
- Rotational Inertia of Point Mass
- Force vs. Displacement
- Acceleration of Cart with Massive Pulley
- Tension vs. Angle
- Simple Harmonic Motion
How It Works
The 6.35 mm diameter, dual ball-bearing shaft extends from both sides of the unit and provides an excellent platform for rotational experiments. The rod clamp (which can be attached on three sides of the sensor) allows the unit to be mounted in almost any orientation. A three-step pulley and a mount for the PASCO Super Pulley make it easy to perform torque experiments.
The heart of the sensor is an optical encoder. Since this is a digital technology, there is no drift or cumulative error; zero always indicates the same point. The resolution, 1° or 0.25°, is software-selectable.
