MCAT sample questions on physical science


The Medical College Admission Test (MCAT) is a computer-based standardized examination for prospective medical students in the United States, Australia and Canada. It is designed to assess problem solving, critical thinking, written analysis and knowledge of scientific concepts and principles. Prior to August 19, 2006, the exam was a paper-and-pencil test; since January 27, 2007, however, all administrations of the exam have been computer-based.

Answer Key:


1. (B). Translational motion is any motion that does not include rotation.

2. (D). The formula indicates that the change in volume will be equal to the volume multiplied by the change in time and the volume expansion coefficient.

3. (C). The center of gravity is determined in order to simplify calculations.

4. (A). The resistivity of a material is one of its most important characteristics.

5. (B). Constructive interference results in combined wave amplitudes higher than any of the wave amplitudes by themselves.

6. (B). Magnification is the ratio of the size of an image to the size of the object that it represents.

7. (D). The fundamental frequency is the lowest frequency that can be sustained by a string.

8. (C). In longitudinal motion, particles oscillate in the same direction that the wave is moving.

9. (B). Ohm’s law asserts that the voltage drop across a resistor will be predictable.

10.( B). An electrostatic force exists between any stationary charges.
