Why do the gas motions of an accretion disk move smaller particles more easily than larger particles?
A) The larger particles tend to be smoother and therefore more aerodynamic.
B) The smaller particles are more dense.
C) The larger particles are more dense.
D) Forces applied to smaller less massive objects result in larger accelerations.

According to Newton's second law of motion, force is directly proportional to mass and acceleration is directly proportional to force, but inversely proportional to mass. Therefore, smaller less massive objects experience larger accelerations when a given force is applied. As a result, the gas motions of an accretion disk move smaller particles more easily than larger particles.
