Drag Force verse force of gravity

Click For Summary
SUMMARY

In the discussion on drag force versus gravitational force, it is established that a large object moving through air experiences a drag force that is proportional to the square of its speed. When falling at half its terminal speed, the drag force can be calculated as a multiple of the gravitational force (Fg). The relationship indicates that at this speed, the drag force is significantly less than the force of gravity, specifically calculated as one-fourth of Fg.

PREREQUISITES
  • Understanding of Newton's laws of motion

A reasonably large object moving though air experiences a drag force proportional to the square of its speed. If an object is falling vertically downward at half its terminal speed, how does the drag force acting on it compare to the force of gravity? express your answer as a multiple of Fg
