Physics Toolbox Accelerometer app for iPhone and iPad

This accelerometer sensor app measures and displays a graph of G-Force vs. Time (s) and Acceleration (m/s/s) vs. Time (s) in x, y, and/or z dimensions, as well as total magnitude.

G-Force data can be recorded and exported as a .csv attachment using a comma as a delimiter.

This app can be especially useful for monitoring changes in acceleration in vehicles or airplanes, and to monitor vibrations of any sort. This app can be used in the classroom to hep students quantify activities with Newtons 2nd Law by taking a mobile device with the app on field trips to amusement park rides, roller coasters, or even in elevators for standard "elevator problems." Because G-Force is the ratio of normal force / weight of the object in question, students can the known mass of the object in question to quantitatively draw force diagrams throughout the objects motion.
