Physics Lab Assistant by Doug Harper Data Acquisition and Analysis for Physics Laboratories

  • Works with any NI-DAQmx-based hardware including myDAQ and NI ELVIS workstations
  • Supports any analog input-based sensor and PASCO motion sensors for measuring position
  • Students design their own experiments by choosing what to measure and what to calculate
  • Calculations can be performed on selected regions of acquired and computed waveforms
  • Students can easily perform repeated trials to test different experimental parameters
  • Supports saving data in tab-delimited text, Excel, and Igor Pro formats

Physics Lab Assistant was designed for the Western Kentucky University Physics Laboratory to allow students to develop their own experimental procedures. The easy-to-use, versatile, and computationally powerful application supports a scaffolded approach as new concepts are introduced.

Physics Lab Assistant is flexible enough to be used for a variety of experiments and scalable to work with simple to complex experiments. Students design an experiment by defining a series of waveforms from sensor measurements and post-acquisition calculations. Acquired waveforms are measured from sensors (e.g., position, force, temperature); derived waveforms are obtained from these using derivatives, integrals, or Fourier transforms (e.g., velocity, acceleration, impulse); and calculated waveforms are built from any of the previous using simple algebra (e.g., momentum, kinetic, potential, total energy). Students can easily perform repeated trials to test different experimental parameters.
