Ooooooooh! Physics!

Photobucket Oooh ahhhh must have been your first reaction to this bag, but your second reaction is man this bag is pretty darn red. The bag appears to be red to our eye because the bag has a low frequency and wavelength. There seven different colors that make up the color white. Red happens to be the lowest frequency and it is easier for the eye to see. the bag is absorbing all of the other colors of the spectrum except for red that is why the bag is perceived to be red. The Ooh is white which means that it contains the colors red orange yellow green blue indigo violet. The three main colors of the sprectrum is red green blue which account for all of the rest of the colors. Whoa these three colors can form all of the colors that just blows my mind!!!

GO TRANSFORMERS!!!!!

Photobucketwell basically i know what your thinking how did I take a picture of optimus prime in its natural habitat. To those who think that way must not know anything about physics. Transformers play a big roll in our daily life. TRansformers work using alternating currents to induce voltage into the second coil. The second coil is only induced when it senses a difference in the current that is produced by the primary coil. This all happening inside the transformer. There are different kinds of transformers out there. Some are used to either increase voltage or others are to decrese voltag. The step down transformer in the pipcture here is transforming the high voltages to 120 volts for the compatability to power my house. Thank God for that transformer or else too much voltage would be at my house.

Its Magneto

PhotobucketIn physics we learned that magnets are used in our life more than we know. Magnets are defined as objects that have an equal amount of north and south poles with aligned domains. The earth itself is a big bar magnet with a south and a north pole. Magnets are related to motors. Using the generator effect we learn the using magnets and copper coils can induce voltage to power things. LIke lets say a radio like i have pictured at the top. As you can see as i crank the radio i am moving the coils around the permanent magnet to an induce voltage to power the radio without the use of the battery. Wow i dont think i could live in a world without magnets!

Photobucket
As you can see me and my fellow classmates, peter , andrew and I went on a hike to embrace natures gift of life. The picture shows the telephone wires that stretch along all over the mountain. Hiking up there we saw birds fly on the wires. Peter was like " what the?!" I had to tell poor peter how it was possible for the bird not to be harmed. I had a brainblast to the day we learned in physics class about voltage differences. The bird did not explode or catch on fire and burn to death because both of its feet were touching the wire thus making the voltage diference zero. Good thing i know my physics or that would have been flustering my brain all day.
