Question

The effect of gravity on a falling object can be modeled by a ball dropped

from different heights. What is a limitation of this model?
O A. Not all objects bounce, even though balls do.
B. Friction with air also affects the fall of the object.
C. Some balls float in water, while others sink.
O
D. The ball can be dropped from varying heights.

Answer 1

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

Step-by-step 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.
