Question

When an object is falling and reaches a constant velocity, the net force on the object is ____ and the weight of the object is equal to____
A. zero; the mass of the object
B. 10; the speed at which the object is falling
C. 10; acceleration due to gravity
D. Zero; the force of air resistance against the object

Answer 1

When an object is falling and reaches a constant velocity, the net force on the object is zero (it's not accelerating), and the weight of the object is equal to the force of air resistance against the object.  (choice-D)
