The video explains terminal velocity, where an object's velocity becomes constant due to balanced forces. Initially, gravity causes acceleration, but as velocity increases, air resistance grows, reducing acceleration until it equals weight, achieving terminal velocity. Deploying a parachute increases air resistance, creating a new, lower terminal velocity. The video uses a velocity-time graph to illustrate these concepts.
