Estudo do movimento bidimensional realizado por uma esfera sobre um plano inclinado

Abstract

In this work, we present a didactic activity to be carried out by students, with teacher mediation, to describe the two-dimensional movement of a sphere along an inclined plane. We constructed the geometric curve that depicts the trajectory of this sphere on the plane, with the help of experimental data extracted from a video produced by us. Then, we also present different geometric and algebraic methods to compare the experimentally obtained curve with those theoretically predicted by the parabolic movement. The teacher’s guide produced by this work offers an opportunity to present students with different ways to describe and analyze physical phenomena with accessible mathematical formulation, as demonstrated by its application with students of 3rd series of high school in a private school in Rio de Janeiro.
