Nonetheless there are several theories that make a good deal of sense and that demonstrate many concepts previously discussed in this unit of The Physics Classroom. The details of how a cloud becomes statically charged are not completely understood (as of this writing). Even today, it is the subject of a good deal of scientific research and theorizing. The scientific community has long pondered the cause of lightning strikes. How do lightning rods serve to protect buildings from the devastating effects of a lightning strike?.What is the cause and mechanism associated with lightning strikes?.In this part of Lesson 4, we will ponder two questions: Indeed, a lightning storm is the most powerful display of electrostatics in nature. Children and adults alike crowd around windows to watch the lightning displays in the sky, standing in awe of the power of static discharges. They're the frequent cause of canceled ball games and golf outings. The fury of a lightning strike is capable of interrupting midday conversations and activities. They send children rushing into parent's bedrooms, crying for assurance that everything will be safe. The rage of a lightning strike will wake a person in the middle of the night. They are never invited, never planned and never gone unnoticed. Lightning storms are inescapable from humankind's attention. Perhaps the most known and powerful display of electrostatics in nature is a lightning storm.
