When is an object that has been dropped from a great height through the air closest to vein in a free fall?

At it's terminal velocity < - - this one?

When it has it's smallest acceleration

When it's velocity downward is largest

When the velocity downward is smallest

- - "Free fall" means no forces acting on the object except for gravity.

- - An object dropped through air has two forces on it - - gravity and air resistance.

- - So we're looking for the part of the drop where air resistance is smallest.

- - The force of air resistance depends on the speed through the air, so the

force of air resistance is smallest when velocity downward is smallest.
