Jumping off the ground or the ground pushing me up???
http://coach-al.smugmug.com/gallery/4687593_r3cxn#277201461_Xp7DW so here is a picture from coach al's photo smug mug. Because coach al doesnt allow us to copy and paste pictures i have a link instead. As you can see im pretty high up in the air. befre i approached the ball i now realized how relevant it is to NEwtons third Law of motion. As i am getting ready to jump i exert a force to the ground but what i now noticed is that the ground is giving back an equal amount of force that my legs exerted. Thats crazy so now i know if i want to jump higher i need to increase the force exerted by my legs so that the ground force push will aslo increase.

Acceleratorrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrssssssssssss!!!!!!!!
As i was driving on the pali i noticed that my speed was constantly changing. At first i was oblivious to the fact of what was causing my car to accelerate, but than EUREKA! i learned in physics class that there are certain parts of my car that can affect the speed of my car. They are called accelerators which increases the speed and or velocity. They are three accelerators in the car. First off the break pedal, when i press on the break pedal my car decreases in its speed and decreases the velocity. The second acccelerator is the gas pedal when i press my foot on the gas pedal im gone my car speeds up and im as fast as lightining. the third Accelerator is a little tricky it happens to be the steering wheel. The Steering whee when you have to make a turn whether you notice it or not slows down the speed and velocity of the car. Physics is cool man

What Lense Should I Use if I'm Nearsighted?
unfortunately my vission is far from from perfect. It was probably from all of those books I read as a child that messed my eyes up but thats not important for now. I have nearsighted vision where i can see things that are close to me but not far. I was wondering what lenses are the most helpful converging or diverging lens. i found out its the diverging lens thats best suited for the job. It is because when i use diverging lenses it helps me focus images from a farther distance

Reflection

As i was watching tv i decided to take a picture at the screen to see what would happen. Baazzoiks !!! to my amazement when i looked at the picture the tv screen i saw this straight flash of light! What the?! you could see the beam of light that the came from the camera's flash onto the tv screen. Because telivisions outer surface is smooth and sleek it was able to reflect the image of the flash of the camera. We learned in physics that light takes the shortest path reflecting off the smooth reflective surface to reach our eyes. If the TV was not smooth and rough it would absorb the light and the light would be scattered in different directions. Boy who knew you could find Physics taking pictures of Jack Bauer!

Ooooooooh! Physics!
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!!!!!
well 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
In 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!
