The Wireless Dynamics Sensor System (WDSS) combines a 3-axis accelerometer, an altimeter, and a force sensor into one unit that communicates wirelessly with your computer or LabQuest 2 using Bluetooth® wireless technology.

Description

Use the WDSS with your Bluetooth-enabled computer and Logger Pro software, or with your LabQuest 2, to collect data free of friction due to cables. Internal data storage capacity allows you to use it as a stand-alone data logger, making it great for roller coaster physics. In addition, you can use the WDSS to do traditional experiments that you do with conventional accelerometers and force sensors.

Using Multiple WDSS

The WDSS can be used alone, with one or more additional WDSS units, or with other Vernier interfaces. The WDSS does not require an interface unless the experiment requires the use of other sensors that are not included in the unit itself. Here are some common combinations:

Experiments and Lab Ideas

The Wireless Dynamics Sensor System can be used as a substitute for both the Dual-Range Force Sensor, the Low-g Accelerometer, and the 3-Axis Accelerometer in any of the experiments for those products.

WDSS Activities Booklet

WDSS Activities Booklet

Download our booklet that contains six activities using the Vernier Wireless Dynamic Sensor System and Vernier Logger Pro software for collecting, displaying, printing, graphing, and analyzing data. Many of the data-collection features of the WDSS are illustrated in these activities, providing a foundation to explore accelerations, forces and their interrelationships. The activities adapted from teacher training materials created by Chris Butlin, Educational Consultant, York, UK.

Here are the seven labs in the booklet:

  1. WDSS Bungee Jumper
  2. Centripetal Accelerations on a Model Centrifuge
  3. Mission to Titan – Investigating Surface Composition
  4. Physics at Amusement Parks
  5. Newton’s Second Law
  6. Newton’s Third Law
  7. Investigating Collisions with Crumple Zones

Amusement Park Physics lab book

Amusement Park Physics

Let your students experience physics with activities from the Amusement Park Physics! Use data-collection technology to study roller-coaster physics and other amusement park rides. Now you can measure altitude changes and acceleration with the Wireless Dynamics Sensor System, then transfer the data wirelessly to your computer for analysis and comparison. Use a Data Vest to hold the Wireless Dynamics Sensor System in place during the ride.

Experiment Ideas

WDSS Experiment Ideas

The Wireless Dynamics Sensor System is the perfect tool for dozens of physics and physical science experiments such as:

  • Studying the motion of a dynamics cart on a track. The WDSS can be mounted on a cart, avoiding the problems associated with wires when using conventional accelerometers and force sensors.
  • Amusement park and playground rides. The WDSS has internal memory and can collect acceleration and altitude data (to get a profile of the ride) for over 100,000 readings over several minutes. You can store multiple runs before retrieving the data.
  • Studying simple harmonic motion by mounting the WDSS as an oscillating mass hanging from a spring.
  • Studying accelerations of skateboarders or dancers with a WDSS mounted on them while data are recorded on a nearby computer.
  • Studying forces and accelerations during circular motion by mounting the WDSS on a turntable or bicycle wheel.
