MCAT Chemical and Physical Foundations of Biological Systems Question of the Day

Practice MCAT Chemical and Physical Foundations of Biological Systems with the production-style question-of-the-day selection for this public URL.

Question 1

For an object traveling in a circle at a constant velocity of 100m/s, which of the following is true?

  1. The object is undergoing constant acceleration
  2. No forces are acting on the object
  3. The radius of the circle is
  4. Only gravitational force is acting on the object
Explanation: Since the object is traveling in a circle, it is constantly changing direction. This means that the direction of the velocity is also changing, even if the magnitude is not. Because the magnitude of the velocity does not change, we can assume that acceleration is constant.
