Pre-Ap Physics Of Lightning

Benjamin Franklin and the Lightning Rod- In 1750 Benjamin Franklin set out to prove that lightning was electricity. Franklin constructed an iron rod with a sharpened end and grew impatient because it wasn’t conducting. He theorized that his sharp iron lightning rod did not conduct any electricity so many people used them for protection from

In the story, “A Sound of Thunder” by Ray Bradbury a man by the name of Mr. Eckels goes on a safari expedition with a company called Time Safari Inc., sixty-five million years back in time. During this expedition they find a Tyrannosaurus Rex and Eckels becomes nervous and freaks out, after that he seems scared and steps off a path which is strictly forbidden as it can alter the timeline, in doing so he crushes a butterfly and changes what will become the present. Through this story Ray Bradbury is trying to convey the theme of all of your actions, even small ones, can grow and form into much greater consequences and outcomes. We shouldn’t be blind to the consequences of our actions.

Ben Franklin was a very curious and inventive thinker. He kept thinking about different ways to experiment with electricity so he came up with an experiment with only a few materials (wire,mobile kite, handkerchief,and two sticks).(”Benjamin Franklin and Electricity”) Franklin

Ray Bradbury is an author used to writing against the norm. Many of his literary works are written in such a way to make the reader think, such as his most famous work Fahrenheit 451, which was a book whose imagery was created entirely by the reader’s perspective. Bradbury (1994) switches up the literary device with ‘A Sound of Thunder’. A Sound of Thunder focuses on three men on a hunting expedition through a time machine, hoping to hunt a T-Rex and proclaim themselves true big game hunters of time. The Expedition goes awry, and one man, Eckels, panics and runs back to the time machine. In the process of his flight, he tramples a butterfly. The other men shoot and kill the dinosaur, and Eckels is sent back to retrieve the bullets from its corpse. The hunting guide learns of Eckels’ misstep, and upon returning to the present, they realize Eckels changed it all for the worse. The expedition ends in a sound of thunder, the fate of Eckels unknown, but assumed. Bradbury uses imagery and diction masterfully in this short story, but a very large focus throughout the story is foreshadowing. Foreshadowing, or the alluding to of events that will eventually take place in the story, remains a centerpiece in Bradbury’s work. How does Bradbury use foreshadowing to bring about a perspective change in the reader?

They are known as convective storms. Cell thunderstorms form in regions where limited vertical wind shear is present. The winds direction or speeds do not abruptly change rapidly. Ordinary storms develop and mature through a cycle, as cell thunderstorms don’t have this development. Different conditions vary from warm air rising, random turbulent eddies and terrain. These are a few that can be a trigger to these more impactful storms.

An electric current exists when there is a net flow of charge through a given area. Electrons flow from the negatively charged region to the positively charged region. This is usually accomplished by using an electrical conductor which allows the electrons to pass freely through the material (Serway, et al. 709). This flow of electrons can generate heat when collisions between the molecules and electrons occur. These collisions then cause the molecules to break apart thus releasing heat. Some common examples of electrical energy are lightning, static electricity, and wiring outlets (Coleman, et al. 82). For the wildland firefighter, lightning is probably the

How tornadoes form you ask? Tornadoes form when different winds from different places met and form this giant spinning destructive cyclone which can be powerful or only cause minor damage. Tornadoes form when hot air from different places and cold air from different places collides which can make a tornado at any speed,

Q9. There are several everyday life situations where we experience this electricity - now we can be more precise and say it is static electricity. Give two examples of everyday life experiences that you can think of and that were not covered here. Describe whether the charging is due to friction, charge separation, or charging by induction.

The kite experiment influenced by the works of other great scientists such as Isaac Newton and Joseph Addison, Franklin wrote his most important scientific work: Experiments and Observations on Electricity. The kite experiment of Benjamin Franklin was to tie a kite with a metal skeleton thread, with its lower end attached to a key. Taking advantage of a thunderstorm, he noted that, trace the comet, electricity is led from the kite to the key, charging outlet. From this, Franklin showed that the clouds were electrically charged and lightning we see are these electrical discharges. Among the inventions of Benjamin Franklin is the lightning conductor, produced from the just mentioned discovery. The lightning rod installed quickly across the country and was a commercial success

“ ‘I’m supposed to go to the Underworld and confront the Lord of the Dead.’...’Find the most powerful weapon in the universe.’...’And get it back to Olympus before the summer solstice in ten days.’ “ The Lightning Thief is a book in which Percy Jackson, the hero, and his friends Annabeth and Grover, must undertake a quest to reclaim Zeus’s master bolt from Hades. “The Hero’s Journey” is a pattern of stages that many heroes experience. Throughout Percy’s quest, the archetype of “The Hero’s Journey” is followed. A few stages of “The Hero’s Journey” that Percy undergoes are The Ordinary World, The Supreme Ordeal, and Confronting the Father.

Benjamin’s experiment with his kite and key helped him to understand lightning. “Mid-eighteenth century scientists and inventors considered electricity to be Franklin’s most remarkable area of investigation and discovery” (Mary Bellis). Franklin’s experiments helped him to create the lightning rod. The lightning rod was a rod that was attached to the highest point of a house or building. The rod would have a wire attached to it that would run all the way to the ground. Lightning would strike the rod and travel along the wire into the ground. The wire connected to the ground absorbed the lightning, preventing the lightning from hitting the house or building. The lightning rod would prevent fires and electrocution. One of Benjamin Franklin’s less known

With the help of his son, William, they hooked up his kite to a silk string, tying an metal key to where the bolt would strike it. Ben’s educated guess was that the lightning itself was an electrical phenomenon, and the electrical effect of the lightning bolt striking it might be able to transfer to another object. Also the causes and effects in the experiment could be recognized as electricity. Concluding this experiment, it successfully showed that the energy from the bolt was static energy. Ben grew more popularity conducting this

So the warm moist air creates clouds of rain and thunderstorm. Adding to that winds with different speed going in different directions assisting in expanding these great clouds of rain and thunderstorm. With

In a lightning protection system, a lightning rod is a single component of the system. The lightning rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum. Copper and its alloys are the most common materials used in lightning

In 1752 Franklin devised another experiment to test if lighting has an electrical charge. He flied a kite carrying a pointed wire in a thunderstorm and attempted to test his theory that atmospheric lightning is an electrical phenomenon similar to the spark produced by an electrical frictional machine (Bruno 406).
