The Centripetal Force Apparatus Goes Wireless

Go Direct® Centripetal Force Apparatus

The new Go Direct® Centripetal Force Apparatus makes it easier than ever to investigate rotational dynamics. Students can investigate the relationships among force, mass, and radius wirelessly—all you need is the Go Direct Centripetal Force Apparatus, a Go Direct Force and Acceleration Sensor, and a device running our free Graphical Analysis 4 app. No additional interface is needed.

With Go Direct Force and Acceleration mounted on the apparatus’ beam, you are ready to investigate centripetal acceleration. Attach the mass carriage, and you can explore Newton’s second law as it applies to rotational dynamics. No tangled wires to worry about. All you need to do is slide the sensor onto the beam, attach the mass carriage, and secure the sensor at the desired location. Select the appropriate data-collection channels in Graphical Analysis 4 for your investigation: Z-axis gyro to capture angular velocity, X-axis acceleration for centripetal acceleration, and/or Force for centripetal force. Then, you’re ready to collect data. As you turn the spindle to rotate the beam, the sensor will apply the force necessary to pull the carriage in a circular motion.

Graph of force vs. angular velocity with a curve fit
Applying a curve fit to the raw data will provide students with clues to nature of this relationship.

The relationship can be further explored as students apply knowledge gained from the curve fit to linearize the data.

Graph of force vs. angular velocity linearized
Linearized data for a rotating mass. What are the units of the slope of the line? Can your students predict the mass given the position on the beam?

Students can quickly devise their own experiments to develop a model for the effect of mass or radius of rotation on the force, and then test the model. Select a mass and position and see if it matches their prediction.

Easily Record and Analyze EMGs with Go Direct® EKG

Normal and rectified EMGs recorded from the forearm
Normal and rectified EMGs recorded from the forearm

Many teachers are interested in using our EKG sensors to record an electromyogram (EMG), the electrical activity produced from muscle contractions. Recording an EMG is straightforward, but there are multiple ways that an EMG can be analyzed. The most robust technique is to measure the integral of the rectified EMG signal, which can easily be done using the Go Direct EKG Sensor.

A normal EMG has both positive and negative deflections. A rectified EMG uses a function that makes all of the EMG deflections positive—the larger the integral, the larger the muscle contraction. In the past, we have offered special Logger Pro and LabQuest files that provide the proper filtering and calculated column support to record and analyze rectified EMGs. But, the Go Direct EKG Sensor makes recording rectified EMGs much simpler. No special files or filter settings are required—just change the channel to EMG Rectified and start collecting data. Then simply measure the integral of the signal in Graphical Analysis.

The sample graph shows an example of an EMG and rectified EMG recorded from the forearm using Go Direct EKG. A digital high-pass filter that has been optimized for recording EMGs is automatically applied to the EMG channel. The EMG Rectified channel returns the absolute value of the EMG channel, making all of the EMG deflections positive.

To analyze the rectified EMGs, simply select the region of the rectified EMG you want to analyze and use the View Integral feature in Graphical Analysis 4. You can even compare the integrals of different rectified EMGs to see which condition produced less or more muscle activity. For example, in the sample graph, the area of the rectified EMG increases with each burst of activity. The first, second, and third rectified EMGs have areas of 0.181, 0.329, and 0.441 mV s.
