Question

Once a falling object has reached a constant velocity, the object ___. A. stops accelerating. B. stops speeding up. C. experiences equal forces of gravity and air resistance. D. all of the above

Answer 1

Once a falling object has reached a constant velocity, the object stops accelerating, it stops speeding up (which is the same as stopped accelerating), experiences equal forces of gravity and air resistance, so it's D.

Answer 2

option D

Step-by-step explanation:

When an object is falling, its speed increases due to the acceleration due to gravity but after travelling some distance, the air resistance comes into role and then the object attains a constant speed. It means the acceleration of body is zero. It stops speeding up.

It experiences an air resistance force which is equal to force of gravity.
