    Presentation

    Study of motion of material point and also of particle systems and rigid bodies: application of kinematics, Newton's Laws and mechanical energy. Understanding and application to simple physical systems.
    It is intended that students acquire the basic skills: S.I. units and dimensional coherence of equations/models; kinematic study of simple and complex movement on the line, and also on plane and space; Relations between motion and its causes; energy, various forms of energy and energy balances and rigid body movement. An introduction to simple periodic movements and material waves is also addressed in this curricular unit. Theoretical and practical understanding of some simple mechanical situations are complemented and visualizef through graphic representations of physic quantities and simple laboratory demonstrations

    Teaching methodologies and assessment

    In the theoretical component classes, in addition to the introduction of the fundamental concepts and relationships in each chapter, "Standard questions" are analyzed to illustrate some practical applications related to the concepts or relationships discussed above. All subjects worked in the theoretical and theoretical-practical classes are also worked out from the laboratory point of view so that students can visualize and concretize concepts and relationships between quantities as well as trajectories. Regarding the practical application and mastery of the problem-solving process, students are challenged to solve in class a known set of proposed exercises and those not solved in class due to different execution speeds of the students, can be solved outside classes and submitted for correction.
