Inertia @ Home Demo: Joe Zerang

I decide to demonstrating the cloth trick. To do this I first placed dinnerware on my dining room table with a cloth under it. Next I grabbed the cloth, and pulled down quickly. After that occurred, the items stayed in place. Inertia states that the tendency of an object to resist change in their state of motion. The items on the table resisted the change in their state of motion, after I pulled the table cloth, and stayed in place.

My mom didn't really have a lot to say except for the fact that you need to pull the cloth down quickly for it to be accurate. She hasn't learned physics since she was in school so I didn't expect a lot. What she said was a correct statement, but she left out any form of scientific evidence with her response. Overall I'd say her response was a 6 out of 10.

Vector Racing: Zerang/Gentile

To win the game one must click on the farthest circle to go farther. Newtons 1st law states that object at rest stays at rest and an object in motion tends to stay in motion. If I didn't click the circle it would stay at rest and not move. And if I kept clicking it the line would continue to move. In newtons second law he states that two unbalanced forces acting upon an object causes acceleration. This was clearly evident in our game because when the applied force on the vehicle is greater than that of the friction, the object will move and continue to accelerate.

In the winter these principles apply to our own driving because when the roads are icy the friction decreases because there is more skidding on the roads. Our cars produce more friction in the summer when the roads are dry and the tires are able to get more traction on the road. This is a big part of why you should be careful in the winter while driving because ideally the care will want to stay in motion. And if there is no traction then the cars tires won't be able to get traction on the roads. So when the car needs to be stopped, it will make it more difficult on the tires and the car itself.

Phaulty In Physics- Joe Zerang

    In this video we see multiple examples of how physics is defied. First we see Wile-E Coyote running from a bus and he's going faster than it. In real life it's rare that you see any animal run faster than a moving car. Next we see him run off a cliff but instead falling straight down like it would normally happen he continues running in the air. Here the laws of gravity are being defied because if anyone or anything were to fall/jump off a cliff, they would go straight down. And Finally we see him running in the air and straight into the neighboring cliff across the way. He then is basically plastered onto the cliff and then after about 3 seconds of being on the cliff he falls straight down... and lives. No one can stay plastered to a cliff and hang on for that long without falling. Overall in the clip the laws of physics are scrapped but the cartoon laws of physics are used. This meaning that no one dies after falling off a cliff and gravity basically doesn't exist when the characters are in mid air.

Gentile/Zerang: Projectile Motion photo

         This photo portrays projectile motion in multiple ways. First we see the quarter back project the football into the air, in a forward direction. When released, the ball is at a constant horizontal velocity until the receiver catches the ball. The vertical velocity is the only factor that is changing during this action.  If thrown correctly the ball should never decrease its horizontal speed, only when it hits the receiver does the speed of the ball change. Now having said that, sometimes wind as well as other weather elements, may effect the way the ball is traveling. For example if it is pouring rain out and the quarter back releases the football -due to weather conditions- it may slip, therefore projecting it in an awkward motion.

Motion Diagram Photo

As one photo would be unclear to the post starting in the bottom right corner reading to left and then continuing on the top you can see the motion diagram image that one would infer. The object is the Swimmer (Kristin) and her motion is through the butterfly stroke. After gliding through the water and coming up she uses her arms to pull her as her legs dolphin kick. The motions work together to create her acceleration. In creating this photo we went through a few decisions. We could have showed you just one photo but the collage makes it more clear in the upcoming motion. We made it by taping a video and then taking the side by side still frames and putting them together so you could see it all working together in one motion.

This picture I took in the mirror shows reflections of light. As my message to Carolyn shows up on the mirror, the light of the image causes us to read it backwards because the words are bouncing off the light. How I kne this was because according to the law of reflections, when both an image and a light strike a mirror, it bounces back. This is essentially why the light makes the image reappear backwards.

The photo above shows reflections of light. when the word physics shows up on the mirror the light/image bounces back making us see the image backwards. this is because, according to the law of reflections, when an image and light strikes the mirror it bounces back the light making the image reappear.

Macks 3D Photo

 I took a picture of an old fan that was at my house. I put the pictures into photoshop and I turned one red, one cyan and the other i just left alone. I pushed the two colored ones to the left and right. In order to view this picture and to get the full 3D picture you need to get one cyan filter and one red filter and put one on the right eye and the other on the left eye.

3-d carolyn shayne

this photo is of Shayne's dog Scout. we created this on photobooth software on a Macbook. In order to see things in 3D each eye must see a slightly different picture. that is why you have different colors, when you put the the glasses on it combines both the colors creating an illusion making the picture appear 3-D. what you need to view the picture in 3-D is to have one red filter for the left eye and one blue filter for the right eye. this is create the most common 3-D glasses -red-blue glasses-.

Shannon and Stephane 3D Photo

To make this picture we took to different pictures both 3 inches apart from each other. With each picture we changed it on photoshop and then we adjusted the photos to make sure that the final picture popped out correctly.  The reason this works is because when you put on the 3D glasses they carry both the red and blue filters. The blue filter blocks out red and green and the red filter blocks out green and blue. Together with these two colors it brings out the red and blue in the photo and makes them pop out.

shayne and carolyn

this photo illustrates when you combine colors what new color appears. for example when you mix red and blue you get magenta. the yellow is a secondary color so when you combine it with blue it looks like cyan since to make yellow you need green and green plus blue creates cyan.

3D Picture: Charley Saram & Jimmy Binder

I made the picture by following the instructions on a website. I took two pictures of the bucket of apples. One picture I moved it so it would be slightly off center. The 3D effect works using colored filters because when seen through the glasses, both lenses have different perspectives that accomodate to each filter. To see it 3d, put on glasses.

Mack Blajda

 In this picture I had two white lights shining on a whiteboard. I put two filters over the lights. One color was blue and the other color was red. When the two white lights were shinning the middle of the whiteboard turned magenta which is the combination of the two colors, Red and Blue.

Shannon Fuchs

Color Addition is when you mix together primary colors and produce new colors. I took the two primary colors, blue and red, and placed the two filters next to white light. By doing this the two colors created magenta (as shown in the picture).

Stephane Antonopoulos

We used the two colors: Magenta and Yellow in which they created the color red. The reason this happen was because it demonstrate color subtraction. The way this happened was by placing the magenta filter, which only allows blue and red light through, on top of the yellow filter, which only allowed green and red light through. With these two filters both blue and green were subtracted and then it only allowed the color red to transmit. 

Charley Saram Color

Color

I made a yellow shade. Using green and red filters i made yellow in the middle. i put the red filter to a light and the green filter to the light to make yellow in the middle. you can see both the green and yellow and red all in the picture. since it is on a white bored the red and green mixed together and just like the color wheel, it made the yellow color. 

Jimmy Color Addtion

In this photo I made Magenta using two filters. The two filters I used was blue and red. I had two white lights and held up the filters to each of them. One light reflected red and the other blue. Both being reflected on a white bored they mixed as they should to make magenta in the middle. You can see all three colors in the picture above. Blue in the top right red on the bottom and magenta in the middle.

DANCING SALT SHAYNE CAROLYN

The insulator was charged with the rabbit fur making the salt stick to it compared to a conductor/ pie dish because the electrons where not able to move from object to object compared to doing it with an insulator. when you rub the rabbit fur against the insulator it makes the insulator negative making the salt come off the pie dish and stick to the insulator.

Dnacing With Salt - Mack and Adam

The Styrofoam which is the isulator was charged by friction while the pie tin which is the conductor was not. This is why the salt sticks to the styrofoam and bounces off the
pie tin. When salt gets charged, the neutral object gets the same type of charge as the charged object that touched it. The salt bounces up and down between the pie tin and the table because some electrons were moving from one to another. We used foam and rubbed it with animal fur. As soon as we put it on the salt the electrons moved from the table which contained less electrons than to the foamwhich had more electrons that caused the salt to sick.

Dacing with salt

The salt bounces off the conductor and sticks to the insulator because the conductor was not charged by friction while the insulator was. When we rubbed the pink Styrofoam with the rabbit fur and put the pie tin on the Styrofoam and then brought the pie tin close to the salt on the metal sheet the salt bounced up and down. The salt bounced up and down because the electrons moved from object to object. When we rubbed the Styrofoam and the rabbit fur and we had salt and the table, The salt sticked to the Styrofoam. The reason being is because the electrons moved from the less electronic object which was the table to the more electronic object which was the negatively charged Styrofoam. The reason the salt sticks to the insulator and bounces of the conductor is because of the metal sheet and the charge on the conductors with their electrons.

Dancing with Salt-Shannon and Stephane

The insulator (Styrofoam) was charged by friction and the conductor (pie tin) was not. That is why the salt sticks to the insulator and bounces off the conductor.
When a neutral object (the salt) touches the charged object(pie tin), the neutral object gets the same type of charge as the charged object. See, the salt bounced up and down between the pie tin and the table because the electrons were moving from object to object.
Later, we used an insulator (foam) and rubbed it with animal fur. As soon as we put it on the salt the electrons moved from the less electron object (the table) to the more electron object (foam) which caused the salt to sick.

shayne and carolyn standing waves

We used the normal setttings for the camera. when we measured the string it was .7 meters; therefore the wavelength is .7 meters also. Our frequency was 42. To find the speed we mulitplied the two together to get 29.4 m/s

Standing Waves Photo-Shannon and Stephane

For these pictures, we used a camera at the regular settings but the one of the settings was set to infinity to capture the wave itself. We set the Hertz to 48.7 and measured the wave itself. The wavelength was .725 meters long. Take the Hertz and multiply it by the wavelength. So that would be .725m*48.7Hz and that equals 35.31m/s. That was how fast the waves were traveling at 48.7Hz.

Standing waves Mack and Adam

For the standing wave I just used the normal settings on the camera. To determine the speed i measured the wavelenght that came out to be .7 meters. I used the frequency given which was 49hz. so to find the speed of the wave i multiplied the two together to get the speed of the wave which is 34.3m/s.

Decibel Levels Around the School-Shannon and Stephane

A scale based on the multiples of ten, which was originally called the logarithmic scale, now called the decibel scale. The faintest sound that a human ear can detect is known as the threshold of hearing. The most intense sound that a human can hear without causing any physical damage to their ears, is more than one billion times the threshold of hearing.

Jimmy & Adam (Decibels Levels Around School)

The faintest sound a human can hear is also known as the threashold of hearing. The range of sounds humans can detect is very large. The scale physicists use is based on multiples of 10. For example, the lowest "level" there is, is level 0. If a sound is 10 times more intense, it is 10db. If its 100 times more intense, it is 20db.

Standing Waves

To capture this image was used an open shudder so we could capture the up and down movments of the string. The way we found the speed was taking the frequency used and finding the wave length of the string and calculating the two together to find the speed. Using our freq. of 49 Hz and Wave length of 70 Cm or .7M we found a speed of 34.3 M/s

Mack & Charley (Decibel levels around the school.)

The range of intensities the human ear can pick up is so large that the scale used to measure the intensity is a scale based on multiples of ten. This scale is also known as a logarithmic scale. This scale is also known as the decibel scale. The threshold of hearing is at level 0db. A sound that is 10 times more intense will be at level 10db. A sound that is 100 more intense would be 20db because of the equation 10*10.

Decibel levels-Carolyn and Shayne

A decibel is a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale. On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB
