Welcome to the Physics course, part of the series for the Pre-Health Sciences Training Certificate. This course and the certificate are designed primarily for learners interested in preparing for and gaining entry to health-related programs and to help address the prerequisites for the Medical College Admission Test (MCAT). This Physics course provides learners with a comprehensive overview of concepts in Physics that are necessary for developing critical thinking skills and applicable to understanding specific bodily functions. It explores the fundamental principles of Newton’s Laws, Energy, Waves, Fluids, Electricity, Light, and Magnetism.
The Physics course is sponsored in part by the International Development Research Centre and the University of the Incarnate Word School of Osteopathic Medicine. Like all NextGenU.org courses, it is competency-based, using competencies based on the Association of American Medical Colleges’ Medical College Admission Test. It uses learning resources from accredited, academic, professional, and world-class organizations and universities such as Rice University. This course was designed by Alixandria Ali BSc; Kabiru Gulma B. Pharm, MBA, MSc., Ph.D.; Marco Aurelio Hernandez, Ph.D., MSc; MSc; BSc.; Felix Emeka Anyiam, MPH, MScPH, DataSc.; Pablo Baldiviezo MD, MSc, DiplEd; Tristan Aaron Wild, BMSc (Hons); Davy Lau; and Cassandra Wild.
