Resumen de Knee Joint Dynamics: An Experiment to Introduce the Concept of Torque to Biomedical and Life Sciences Students
Classical dynamics is a fundamental pillar of any general physics course. The presentation often starts by showing Newton’s three laws and their applications to static and dynamic scenarios, treating objects as particles that can be displaced but not rotated. Common examples include a mass sliding over an inclined plane1,2 or a bullet shot at a determined angle with the floor.3 In all those cases, macroscopic objects are considered as point-like, and the problems can be solved by applying Newton’s laws to the center of mass of the objects.
