QNET Physics and Dynamics Board

This product is no longer available.

The QNET Physics and Dynamics board is a hands-on validation platform to teach and demonstrate fundamentals of dynamic modeling and analysis. Designed exclusively for NI ELVIS platform and LabVIEW™ software, the board exposes students to a series of most common dynamics topics including friction, systems of forces, kinetics of particles, energy and momentum, and more.


Product Details

The QNET Physics and Dynamics board consists of a catapult with adjustable release angle and a sliding mass arm with adjustable incline. The angles of the catapult and the sliding mass arm are measured by a single-ended optical shaft encoder. The behavior of the catapult and sliding mass experiments are controlled by electromagnets, releasing the sliding arm and the catapult arm. Also included are a set of classic mechanical elements such as springs, pulleys, masses with different surface materials, and pendulums, that can be set up in various configurations for a wide range of experiments.

  • Multiple platforms and components for creating a wide range of experimental configurations
    • Sliding mass with 4 different surfaces (PETG, styrene, rubber, Teflon)
    • Two 100 g and 50 g weights
    • Spring
    • Return pulley attachment
    • Two pendulum rods with different lengths
  • High resolution optical encoders to sense position of the catapult and sliding mass arms
  • Electronic release of sliding mass and catapult arm
