This study is focused on the concept and formalism of work done and potential energy on the very fundamental level. A detailed analysis of the incomplete presentations of the topics found a major misconception that precluded acknowledgement of existence of certain nonradial effects caused by classical radial/center-bound gravitational force fields…

Students entering into higher education institutions today represent America's growing diversity. Much of the increase seen is due to the large numbers of students from different ethnic backgrounds and the changing demographics of immigrants who have migrated to the United States. As a result of this research, the perceptions and experiences…
