SUMMARY
The work done by gravity on a raindrop weighing 2.76 x 10^-5 kg falling 131 meters is calculated as W = (mg)*d, resulting in 0.03543288 J. Since the raindrop falls at a constant speed, the work done by air resistance is equal in magnitude but opposite in direction to the work done by gravity, also measuring 0.03543288 J. This balance indicates that the upward force of air resistance counteracts the downward force of gravity, preventing any increase in kinetic energy.
