Test prep


This collection is being developed for the revised MCAT® exam that will first be administered in spring 2015. Videos will be added to the collection through fall 2014. All content in this collection has been created under the direction of the Khan Academy and has been reviewed under the direction of the Association of American Medical Colleges (AAMC). All materials are categorized according to the pre-health competencies tested by the MCAT²⁰¹⁵ exam; however, the content in this collection is not intended to prescribe a program of study for the MCAT²⁰¹⁵ exam. The content is also included in the Pre-health Collection within MedEdPORTAL’s iCollaborative sponsored by the AAMC: www.mededportal.org/pre-health *MCAT® is a program of the AAMC and related trademarks owned by the Association include Medical College Admission Test, MCAT, and MCAT²⁰¹⁵.

Vectors and scalars

4A: Find out what makes vectors different from scalars! Find out how to break vectors into components, and go over the different ways to represent vectors. By Sal.

Normal forces

4A: Learn about the normal force, and try some examples that demonstrate how the normal force is affected by the motion of an elevator, as well as how the normal force affects friction. By Sal.

Work and energy

4A: Learn about the concepts of work, mechanical advantage, and power. After understanding the principle of conservation of energy, you can apply it to different types of energy including kinetic energy, gravitational potential energy, and spring potential energy. Finally, learn about the conservative force as well as how to find mechanical advantage. By Sal and David SantoPietro.

Fluids at rest

4B: Learn the physics behind fluids at rest. Some of the ideas explored are density, pressure, Pascal's principle, Archimedes' principle, buoyant forces, and specific gravity. By Sal.

Gas phase

4B: Let's learn about gas phase chemistry! Discover the history and application of the ideal gas law. We'll walk through topics like temperature, STP, partial pressure, and the difference between real gases and their ideal counterparts. By Ryan Patton.

Spherical mirrors

4D: These videos go over the images formed by curved mirrors. It will be explained what a real and virtual image is and how to draw ray tracings to determine the location and size of the image formed. By David Santo Pietro.

Redox reactions

4E: Discover how to assign oxidation states/numbers in redox reactions, then go on to balance redox reactions! By Jay.
