O1 - Development of a critical spirit that allows understanding, Interpreting and applying knowledge in the field of physics and technology related to this area;
O2 – Application of logical reasoning to concrete problems, using tools from physics and mathematics;
O3 – Knowledge and development of skills for analysis, and for solving problems in the field of Electrostatics, namely in the study of electrostatic phenomena associated with electrical loads at rest. In this context, it is intended to develop the ability to observe, measure and analyze physical phenomena associated with the main properties of Electrostatics, such as electric charge, electrification, electric force, electric field, electric potential, electric potential energy and electric current.
