物理学位是大学提供的最古老的学位之一。多年来，物理系一直致力于指导学生，并为他们提供在物理的几个分支中进行研究的充足机会。该系的学生和教职人员经常被大学，犹他州和美国所认可凭借着名望的奖项，美国大学的物理学专业学生被提名为美国国家科学基金会的研究生，金水学者和罗德学者，并且学生经常在研究会议上获得奖项。物理课程很小，在鼓励，指导，研究，和便利。学生可以从以下几个研究领域中进行选择：复杂性，领域，天体物理学和时空理论，等离子物理学，空间科学和表面物理学。
Physics degrees are among the oldest degrees offered by the university. Through the years, the Physics Department has remained dedicated to instructing its students and providing them with ample opportunities for research in several branches of physics. The students and faculty of the department are frequently recognized by the university, the state of Utah, and the nation with prestigious awards, physics students at USU have been named National Science Foundation Graduate Fellows, Goldwater Scholars, and Rhodes Scholars, and students frequently win awards at research conferences. Physics classes are small, providing students with faculty attention where research is encouraged, mentored, and facilitated. Students can choose from several areas of study, which are: complexity, fields, astrophysics, and spacetime theory, plasma physics, space science, and surface physics.<br>Upper Atmospheric Physics (MS):<br>This specialization is concerned with the physics of space. Students study topics such as electromagnetism, plasma physics, solar-terrestrial physics, and space environment and engineering. This specialization is designated as a Western Regional Graduate Program, which means students from participating western states qualify for in-state tuition.
