//** Questions:\In a Paragraph or more tell the class your Interests, favorite subjects, favorite topics in science, least favorite topics in science, and what you Would Like to Learn This Year. My interests are science and sports. My least favorite science topic is simple machines.My reason is because I Iearned it last year so it was the least exhilarating topic I ever came across.Now on the other hand my favorite subject on science is erosion. Why? because I learned about chemical erosion and what it does like break down gates because of its corrosive acid, for example acid rain. What I would like to learn this year is more about the adaptation of animals over time as there habitat change. Also I would like to learn more about atoms like protons, neutrons, and electrons what they do and how they form.The final thing I would like to learn is the formation of islands due to under sea volcanoe because I do not comprehend how the volcanoes occur to be under water.This is what I take interest in and my favorite topic on science and what I would like to gain knowledge in science this year. **//

Mr. Hankins

Tension is a part of physics. Tension is the magnitude of a pulling force exerted.

Tension is exerted by a cable, leash or rope. It is an opposite of compression.

Tension is measured by Newton’s or sometimes pound forces.

Always tension is measured parallel to which it applies to.

There are two systems held by the string, which are net force and the equilibrium.

The equilibrium is the sum of total forces in zero

The system of the net force due to an uneven force exerted. On it, therefore the total of all forces are not zero speed and net force always lives together.

A string is assumed to have negligible mass.

That is my research for tension.

My next topic is force.

Galileo is the first person to show the various types of forces.

Even though Galileo pointed it out, Isaac Newton created the equation for force in his second law.

When you think about it you use force to push objects like doors and heavy boxes.

Force is the possibility to push any object depending on how strong it is.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Force is any influence that causes an object to go through a change in velocity and change direction.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Force can also be explained by the understanding of push and pull.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Force is a combination of magnitude and directions making the vector quantity.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">The vector quantities means the forces follow a different set of mathematical rules than physical quantities.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">When, the two factors, which are magnitude and direction, act to an object.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Newton second law which was force and its formula is F=ma.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Now it is different but equal terms the original version says that the net force acts upon an object when momentum changes.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Tension is measured in a unit called Newton’s.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">The SI symbol for force is F

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Force is used every where you go whether it is opening a door pushing a box.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Gravity is a force because it keeps everything on earth.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Without force there would not be anything holding us to earth.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Example of force is when two students are pulling on the rope in the same direction

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Without comprehending the other types of forces it is impossible to get the net force.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Another example would be somebody hurls a rock in the air and catches it without applying force.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">The rock s inertia is associated with its constant speed.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">One other example is a car at a constant speed.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;"> The law of physics does not change from being at rest.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Inertia applies equally to constant speed and motion as it does rest.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Inertia can be explained for objects in different types of motion.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Even those that are not strictly at constant speed.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">Albert Einstein explained the principles of inertia when he explained the frames on constant acceleration.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">The frames such as free- falling toward a gravitating objects that were physically equal to the inertia reference.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 16px;">r example, that is the explanation for weightlessness in space and free fall orbit.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 18.6667px;">In conclusion that is why I think Newton’s law of motion is discernable in this condition.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 18.6667px;">Concepts to speed such as thrust increases the acceleration of an object.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 18.6667px;"> Concepts like dragging decrease acceleration in objects.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 18.6667px;">Additionally, torque causes changes in rotational speed.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 18.6667px;">All of these terms increase or decrease speed in an object.

<span style="font-family: 'Arial Rounded MT Bold','sans-serif'; font-size: 18.6667px;">After this research, I have more knowledge to help me in my project.

Controlled variable same place same ,same items, same position the egg was dropped,same height, same egg Dependent variables the side that withstands the most pressure on the egg. Independent variables Size of egg. (for project1-3) materials quail eggs white eggs journal scale 4small cans 4large cans fingernail scissors

Problem statement which part of the egg takes the most pressure? Hypothesis If the sides are easier to crack i think the dome is harder. If the egg is small i think the big egg holds more pressure. If the domes is harder then it will take more pressure.

Procedures First wrap egg in masking tape then take fingernail scissors and poke holes in it empty out contents of egg Then cut in half egg and place it on scale. after that place cans on the egg until it cracks. Finally record ounces in journel for data.

abstract The purpose of the experiment was to find out how much pressure an egg can hold,what type of egg and what sized egg holds the most pressure.

bibliography strength of an egg retreived11/1/11 7:55 P.M http://www.sciencefairadventure.com

Application This experiment can be used in everyday life when cooking you know the easiest part of an egg to crack is its side.

results I was right on all my hypothesis the smaller the egg the least amount of pressure it can take. another result is the more nutrients in the egg the stronger it is so the white egg was stronger. Finally the dome is the strongest part of the on all of the sides

conclusion In conclusion I was right an my data has taught me that the strongest part of an egg is its dome
