Question

Which of the following descriptions best describes all of the factors that need to be considered when determining an object’s terminal velocity?(1 point)
Responses

the object’s weight and area it presents
the object’s weight and area it presents

the object’s weight, length, and width
the object’s weight, length, and width

the object’s weight and area it presents, as well as air density
the object’s weight and area it presents, as well as air density

air density and the object’s drag coefficient

Answer 1

the object’s weight and area it presents, as well as air density

Reason: terminal velocity is reached when weight = drag. Drag depends on air density (ρ), the object’s cross‑sectional area (A), and the drag coefficient (C_d), so weight, area, and air density (and in full detail C_d) determine terminal velocity.
