Resumen:	En este trabajo, que forma parte de una Tesis de Maestría en Enseñanza de la Física ya defendida, presentamos limitaciones e incomprensiones, de estudiantes de cursos básicos universitarios de carreras científico tecnológicas, en torno al establecimiento y reconocimiento de las condiciones de validez de leyes fundamentales de la Mecánica Newtoniana. Los resultados parecerían mostrar vínculos importantes entre la comprensión de aspectos epistemológicos y conceptuales de la Física cuyo reconocimiento y caracterización pueden contribuir a la formulación fundamentada de estrategias educativas más eficientes.
Notas:	Trabajo presentado en la Sección Ciencias Naturales.
