Motion in the Presence of Resistive Forces in Physics

Air and water push back, and the harder they are pushed the harder they push. That single feedback loop is what separates this topic from ordinary constant-acceleration motion, because the acceleration keeps shrinking as the speed grows until it disappears altogether. The speed it settles at is the terminal speed, and it depends on whether the resistance grows in proportion to the speed or in proportion to the square of the speed. The blocks cover both models, the terminal speed each one predicts, and how the speed and the distance evolve while the body is still approaching that limit.
