Answer: Air resistance just balances the force of gravity
Explanation As a raindrop falls: Initially, it accelerates due to gravity. As its speed increases, air resistance (a drag force) also increases. Eventually, a point is reached where the upward air resistance equals the downward gravitational force . At this point, net force = 0 , so acceleration stops , and the raindrop continues falling at a constant speed . This constant speed is called terminal velocity .
