Força de atrito

Abstract

The Educational Digital Resource - Frictional force was developed having concept maps design as main methodological base. According to Moreira, "as long as students use concept maps to integrate, reconcile and differentiate concepts (...) they will be using the concept mapping as a learning resource." Together with the presentation of a conceptual map on frictional force, aiming to briefly review the concepts, this RED has three situations traditionally considered in the teaching of that content. They are: object at rest on an inclined plane, object on an inclined plane on the verge of motion and object sliding on an inclined plane. Such situations are explained step-by-step, for example, with details of the vector decomposition of forces. We point out the demonstration of a direct application of physical concepts in a common context of the university everyday life. Thus, the student can achieve a significant learning about friction, improve their mathematical skills, and may extend their own conceptual map.
