Welcome to the Physics course, part of the series for the PreHealth Sciences Training Certificate. This course and the certificate are designed primarily for learners interested in preparing for and gaining entry to healthrelated 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 competencybased, using competencies based on the Association of American Medical Colleges’ Medical College Admission Test. It uses learning resources from accredited, academic, professional, and worldclass 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.

There are eight (8) modules to complete, which provide an introduction to:
Module 1: Translational Motion
Module 2: Forces and Newton's Laws
Module 3: Momentum, Work, and Energy
Module 4: Waves
Module 5: Fluids and Solids
Module 6: Electricity and Magnetism

The course requires the completion of all quizzes, discussion forums, and practical activities to receive a course certificate. Practice quizzes are available throughout the course and contain 10 MultipleChoice Questions each. After you’ve completed each module, quiz, and learning activity, at the end of the course, you’ll have access to a final exam consisting of 40 MultipleChoice Questions and a chance to evaluate this course. Participants have up to three opportunities to take the final exam and achieve the required passing score of >=70%. Once you’ve passed the final exam and completed the evaluations, you will be able to download a certificate of completion from NextGenU.org and our course’s cosponsoring organizations.
