Question

1. what is the effect of air resistance on the acceleration of falling objects?

Explanation:

Air resistance acts in the opposite direction of the motion of a falling object. According to Newton's second - law ($F = ma$), when air resistance is present, the net force acting on the falling object is the gravitational force minus the air - resistance force. So the acceleration of the falling object is reduced compared to the situation where there is no air resistance (free - fall acceleration).

Answer:

Air resistance reduces the acceleration of falling objects.
