multiple choice question
a ball is falling to the earth. ignoring air resistance, which of the free-body diagrams shown in the figure is the correct diagram for the ball?
○ b

Explanation:

When a ball falls to Earth and air resistance is ignored, the only force acting on the ball is its downward weight (gravitational pull from Earth). A normal force only acts when the ball is in contact with a surface, which it is not during free fall.
