5.11.1. Justification ↑ Back to top
Physics I introduces the foundations of classical mechanics as a mathematical and experimental discipline. Through the study of kinematics, Newtonian dynamics, conservation principles, and rotational motion, students acquire the analytical tools needed to model and solve problems of the physical world. This course provides the indispensable foundation for the study of oscillatory, wave, and electromagnetic phenomena addressed in subsequent courses.

- Apply the principles of work, potential energy, and conservation of mechanical energy to systems with conservative and non-conservative forces.
- Solve particle-system dynamics problems using conservation of linear momentum and collision analysis.
- Analyze rotational motion and angular momentum dynamics in systems of particles and extended bodies.
