Without the magnets, when the marbles is rolled and hits another set of marbles, the last marble moves in a similar constant speed as the ball that had been rolled. We added the magnets, which were put in front of the marbles and we rolled one marble towards the magnets and the force of the magnets made the center marbles move at a higher speed than the first marble that we had rolled.

Vector Racing: Molly and Pearl

1) How does winning the game require you to apply Newton's 1st and 2nd laws?
The game applys the laws by showing the rate the car needs to accelerate and the direction it goes on turns, for it to successfully make it around the track without crashing into the sides.


2) How do these principles apply to your own driving especially in winter?
The games shows when a person needs to accelerate, decelerate, and maintain the the speed, especially on turns.

Water being drained off a cup

 

This image illustrates a projectile motion because once the water is spilled out the cup, it makes a parabola motion. The water makes a slight curve once it is being spilled out of the cup.

Tom and Jerry

Occurrance of falling 1:28

 

 

Claim: In the cartoon, Tom and Jerry, Tom is seen falling from the top of the dock into the water. The motion that was impossible in the scene was at 1:28 when Tom was falling off horizontally at first, and then stops in the air for 22 seconds exact and then falling into the water below of him.

 

Evidence: A person cannot stay in the air for 22 seconds and waits to fall down. In the scene Tom goes horizontal to the left and then falls straight down after 22 seconds.

 

Reasoning: This segment could not happen whatsoever because a person cannot stay in the air for 22 seconds and floats there just waiting to fall down, and also Tom had to check if he really was in the air before he had fallen into the water. When a person falls they are falling horizontally and vertically at the same time.

Pearl and Molly's Motion Diagram Photo Project

 

 

The motion of the ball is rolling/ bouncing down the stairs. The ball decreaces its spped once it reaches the ground.

The photo was created by using a digital camera to create a constant time interval motion diagram photo.

Mirrors and Lenses Photo Hannah

This photo displays reflection and refraction in many ways. One way it displays reflection is, the light from the sun reflects against the camera lens. Another way this photo displays refraction is, the camera breaks up the sunlight. You can tell from this that this forms a ray. The sun appears blurry in this picture because of the lights rays being reflected and refracted.

Candace and Cecilia Mirror and Lenses Photo Project.

This image shows the reflection of light in a lens. It shows reflection because the shutter is held open while the lens is capturing the movement of the light, which happens to be a flashlight. It is created by the movement of a light using a slow camera shutter speed, to create an image. Because this type of photography requires a long exposer, it is usually dont at night, or in this case, a dark room.

Create Your own 3-D Photo Farhad, Candace and Cecilia

`This was a picture took in Physics class to show 3D effect. The picture was edited in phtoshop to give it it's 3D effect. We took two pictures one picture was the main one, the other was exactly 3 inches to the right of the normal picture. We removed RGB the three main colors from the first photo, which gave it it's faded black and white colors. Then we merged the 2nd picture with the first picture and we saw three colors black blue and red, and this is why we got a 3D effect. This works because if there is two pictures from a distance attached with no colors then you see the picture as one. You see the picture as one picture with the same color. The only way you see this picture in a 3d effect is with 3D glasses that have red and blue lenses.

Farhad-Measuring the Speed of Light in Your Microwave

 

 To find the Speed of light I had to recall the wave equation, which is v=λf. To find the wavelength I had to do an experiment. First I grabbed a slice of bread, I added a thick layer margarine to the top. Then I put it in the microwave for 40 seconds to let the margarine melt. After the 40 seconds, I took it out and got a ruler to measure the "hotspots". The "hot spots" were about 4cm, I converted cm to meters. Then I did my calculations. The wavelength was 0.04m, the frequency was 300mHhz.The velocity is 12m/s

Color addition Farhad

This is a picture of lights. You can see the red and blue lights being mixed together making a magenta color. The blue and green lights also mix to make cyan.

Color Addition Candace and Cecilia

This picture shows the addition of color by adding food coloring to the water. When you mix all the colors together you get black, but as you can see when you mix the red and blue it makes a deep magenta color. Also, when you mix the blue and the green food coloring you get cyan. 

Measuring the Speed of Light in Your Microwave -Cecilia and Candace

 In this experiment we found the speed of light. Microwaves create standing waves. The antinodes are the "hot spots". First I got a slice of bread and I added a thick layer of margarine on top. Candace put it in the microwave for 50 seconds. We watched the margarine melt. Then I took the slice of bread out of the microwave and Candace got a ruler and measured the "hot spots". The "hot spots" were about 6cm. The wave equation is v= λf. the wavelength is 6cm. the frequency is 2450mhz which I got from my microwave label. I converted cm to meters. I did 0.06m x 2450m = 147000. the velocity is 147000m/s.

3D photo Hannah

The Picture was made by following the 3D steps from the NASA website. For example, one step was to convert both images to gray scale. Another step was to, convert the right photo to RBG. A final step was to, merge the left and right photo together. The 3D effect works using the filter glasses because, it pops out the RBG colors so you can see the effect. In order to see the photo, the viewer needs to put on the 3D glasses 

Color Addition/Subtraction Hannah period 8



This photo illustrates many additions. One addition it illustrates is, the yellow. The colors red and green were mixed together to make yellow. This would be considered color addition. Another color that was added was, cyan. The colors green and blue were mixed to make this color. This would be considered color addition. A final color subtraction that was made in this photo was, the blue star and the R. The subtraction that was made was, blue. The subtraction was blue because, the color that turned out was green.

Ev & Elpidio Salt Extension

The reason why the salt stick sticks to the insulator is because the salt is neutral and the insulator is negative. which means that the salt would stick to the insulator and bounce off the conductor. our proof is that when we charge the plastic rod and then hold it above the salt, the salt is forced upwards and sticks to the rod. and when we charge the pie tin and place it above the salt, the salt bounces right off becuase it is the same charge as the salt.

Candace, Cecilia, Farhad Dancing and Sticking Salt Mystery

In this extension we had to figure out why salt bounces off conductors and why it sticks to insulators. The salt sticks to the insulator because the electrons can not pass through the pipe. The salt bounces off the conductor because the electrons in the salt are being repelled off the pie tin. Conductors carry a charge, but insulators do not. So the insulators can not attract objects with the opposite charge.

Dancing and Sticking Salt Mystery-Hannah

In this extension, I determined why the salt sticks to the insulator but bounces off the conductor. I determined that it's due to the fact that, conductors carry a charge while insulators do not. The evidence I have for this is the first experiment and the third experiment. In the first experiment, the salt was able to stick to the tube due to the fact that the tube was a conductor. But in the third experiment since I brought a charged insulator over it, it did not work because insulators do not carry a charge. The reasoning I have for this once again is, conductors will always carry a charge not matter what so they can attract objects easily. On the other hand, insulators do not carry a charge so they can't attract other objects with an opposite charge.

The frequency was 67.5hz. There were 5.5 waves. The wavelength was 2.79meters. To find the velocity you multiply 67.5hz and 2.79m and the answer you get is 18.83m/s.

Decibel Levels around the School- John and Hannah

Hallway: 26 Hz

Air Room: 89 Hz

Guy lifting weight: 71 Hz

Classroom Decibel Level: 30 Hz

In this extension, we determined decibel levels in different areas of the school. A decibel is a unit used to express how loud or soft a sound wave is. The decibel scale works by measuring how much frequency there is in a sound wave. Once again, this helps determine how loud or soft the sound is.

Standing Wave Photo Project John and Hannah

In this extension, we determined the speed for a standing wave. But in order to do this, we first had to take a picture. Now in order to do this picture, we just took a regular photo. Next we found the speed of the wave. Our frequency of our wave was 30 Hz. The wavelength was 2.5 m. We then multiplied that and got 75 m/s.

Candace, Cecilia, Farhad. Decibel levels around the school

A decibel is an unit for relative loudness. The decibel scale is a logarithmic scale. In order to move up by the same amount from any starting point, you don't add the same amount, you multiply.

Energy Skate Park Challenge Farhad Cecillia

What does it mean when we say energy is conserved?

We think it means allenergy you had before the reaction is equal to all the energy you have after the reaction. It's a consequence of the observed fact that the laws of physics don't appear to change over time.  It helps alot with solving problems.

How does friction affect conservation of energy?

It would only affect it by potiential energy to never go down even if the kinectic energy would go up, it wouldn't make a difference.

How can you numerically predict the velocity of a skater at the bottom of the hill?

I think that you ccan use the velocity formula. V=d/t. To find it you will need to find distance and time.
