The content analysis technique was used to investigate whether in the texts the conservation of energy is presented as a physical law or as a theorem that is proved by appealing to the work and kinetic energy theorem, also to characterize the way in which it is stated. said law and the meaning given to it. It was found that the conservation of energy is mostly established from the theorem of work and kinetic energy, it is stated in a positive way and conceived as both a constant of movement and an invariant of the universe. Se inspeccionó una muestra de diez libros de texto de Física que se emplean usualmente en cursos introductorios de Física de carreras vinculadas a las ciencias exactas y experimentales, ofrecidas en universidades argentinas; con la finalidad de caracterizar el tratamiento dado a la conservación de la energía. Se usó la técnica análisis de contenido para investigar si en los textos se presenta la conservación de la energía como una ley física o como un teorema que se demuestra apelando al teorema de trabajo y energía cinética, asimismo para caracterizar la forma en que se enuncia dicha ley y el significado que se le otorga. Se encontró que mayoritariamente se establece la conservación de la energía a partir del teorema de trabajo y energía cinética, se la enuncia de manera positiva y concibiéndola tanto como una constante del movimiento como un invariante del universo.
