Answer:

B. Friction with air also affects the fall of the object.

Explanation:

The limitation of this experimental design is that friction with air also affects the fall of the object.

  • Therefore, it is difficult to measure effect of gravity on falling objects.
  • Air resistance cause friction in the movement of an object falling.
  • Frictional force resists the motion of an object subject to free fall.

Therefore, the experiment will be biased due to the influence of the frictional force.
