The data was collecting with the TI-Nspire CX using Vernier DataQuest app. The square brackets can be moved to automatically change the quadratic and linear regressions. Note the relationship between the position-time and velocity-time graph.
y=1/2(acceleration)*time squared + (initial velocity)*time + initial position.
v = acceleration*time + initial velocity
The motion detector used to collect this data was the CBR2. It can plug directly into the TI-Nspire without the need of any additional interface. Other motion detectors, like the original CBR or Vernier Motion detector can be used, even several at the same time, when the aid of the TI-Nspire Lab Cradle. http://www.vernier.com/calc/ti-nspire/cradle.html . This is a great STEM resource and teaching/learning tool.
