• Resumen

  • In an article in this journal, it was shown that air resistance could never be a significant source of error in typical free-fall experiments in introductory physics laboratories. Since projectile motion is the two-dimensional version of the free-fall experiment and usually follows the former experiment in such laboratories, it seemed natural to extend the same analysis to this type of motion. We shall find that again air resistance does not play a significant role in the parameters of interest in a traditional projectile motion experiment.
