Effects of Drag Force on Free Fall (12:34)
The proportionality constant drag force equation is introduced. The acceleration of the ball for its entire path is discussed. Terminal velocity is derived. The time going up vs. time going down is determined and demonstrated. The position, velocity, and acceleration as a function of time graphs are estimated.
This is an AP Physics C: Mechanics topic.
