Question

what is the effect of air resistance on the acceleration of falling objects?
air resistance increases the acceleration of falling objects.
air resistance decreases the acceleration of falling objects.
air resistance does not affect the acceleration of falling objects.
air resistance doubles the acceleration of falling objects.

Explanation:

Air resistance is a force that acts in the opposite direction of the motion of a falling object. According to Newton's second - law (F = ma), when an additional opposing force (air resistance) acts on a falling object, the net force acting on the object is reduced. Since acceleration is directly proportional to the net force (a = F_net/m), a reduced net force leads to a decreased acceleration.

Answer:

Air resistance decreases the acceleration of falling objects.
