Projectile Motion in Real Life

نویسنده

  • MICHAEL ÖSTERLUND
چکیده

Projectile motion is a fundamental concept in basic physics courses. The often used simplified calculations, where air resistance is neglected, are obviously not relevant for many real life events. Using a video camera and computer software, students can investigate the influence of air resistance on for instance the trajectory of a football. The video sequences are digitised and the xand y-positions of the ball in every frame are registered together with the actual time. Comparisons are made with theoretical calculations performed using both an ordinary spreadsheet program and software specially designed for dynamic simulations.

Parametric programming : An illustrative mini encyclopedia ∗

Parametric programming is one of the broadest areas of applied mathematics. Practical problems, that can be described by parametric programming, were recorded in the rock art about thirty millennia ago. As a scientific discipline, parametric programming began emerging only in the 1950’s. In this tutorial we introduce, briefly study, and illustrate some of the elementary notions of parametric pr...
