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 WDSSThe 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: Two WDSS units connected by Bluetooth to a single computer for Newtons Third Law experiments.A WDSS used with a Vernier interface, Motion Detector, and a Dual-Range Force Sensor for impulse-momentum experiments.A WDSS with a Vernier interface and a Dual-Range Force Sensor for Newtons Third Law experiments.A WDSS, a Go!Motion, and a Vernier Dynamics System create an elegant impulse-momentum experiment setup.

The Low-g Accelerometer is the best choice for most acceleration experiments, including Newtons second law, simple harmonic motion, and the relationship between acceleration and force. It can also be used to study one-dimensional motion of a car (real and toy), an elevator, a pendulum bob, or an amusement park ride. Using Multiple AccelerometersYou can simultaneously measure the signals from two or three accelerometers mounted at right angles to measure acceleration in more than one dimension. To study acceleration in a plane, mount two accelerometers at a right angle. This is a great way to study accelerations in an automobile.Mount three accelerometers at right angles, or better yet use our 3-Axis Accelerometer, to study acceleration in every direction. This is useful for studying the complex motion of an amusement park ride or while bungee jumping.

The 3-Axis Accelerometer consists of three 5 to +5 g accelerometers mounted in one small block. Using the appropriate data collection hardware and software, you can graph any of these components, or calculate the magnitude of the net acceleration. The 3-Axis Accelerometer can be used for a wide variety of experiments and demonstrations, both inside the lab and outside.

The Vernier Anemometer is an impeller-type anemometer that measures wind speed in the range of 0.5 to 30 ms (1 to 67 mph). The Anemometer fits in your palm for wind study measurements in the field. A standard camera mount on the back and an accessory rod allows you to position it in wind tunnels or in front of fans for wind turbine experiments.

Unlike a traditional electroscope, the Charge Sensor can make quantitative measurements. Numerical measurements improve many electrostatics experiments, such as charging by induction, charging by friction, and charging by contact. The sensor can also be used to measure charge polarity. An extremely high-impedance voltage sensor with a 0.01F input capacitor makes these measurements possible. The sensor has three operating ranges and a zeroing switch to discharge the input capacitor.

Use this sensor to explore absorbance and percent transmittance in a variety of experiments including Beers law (absorbance vs. concentration) and kinetic studies (concentration vs. time). Students select between four wavelengths (430 nm, 470 nm, 565 nm, 635 nm) to set up their experiment. Go Direct Colorimeter features one-step calibration for all four wavelengths. Its as simple as inserting a cuvette of distilled water and pressing the Calibrate button. Go Direct Colorimeter can be used in a variety of experiments: Conduct Beers law investigations.Determine the concentration of unknown solutions.Study changes in concentration vs. time.Monitor reaction rates.
