How fast in m/s is the moon orbiting around the earth if it has orbital period of 27 days(2,330,800 seconds) and orbits at a radius of 380,000,000 m?

C = 2 pi R     circumference of orbit

V = C / P      speed of moon by dividing circumference by period of revolution

V = 2 pi R / P_ = 2 pi 3.8 * 10E8 m / 2.3308 * 10E6 sec = 1024 m/s

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

c.the charges if the proton and electron and gravity
