Essays on Physics

Physics is part of our everyday life in ways that we can’t even imagine. It is the reason why the sky is blue, the grass is green, and so much more. We never think of how things happen or why, because we are so used to everyday life that it never crosses our minds to stop and think. Physics affects our health, energy, communication, transportation, electronics, and much more. It has to do with pretty much everything we, and everybody else does. It’s hard to go throughout the day not doing something that involves physics. Physics also has everything to do with energy, velocity, mass, force, acceleration, and gravity.

Alternatives to Fossil Fuels

The conventional source of energy like coal, the petroleum, etc, will probably be exhausted up within a time that the humanity might foresee. In addition, according to Hordeski (2002), fossil fuels such as petroleum, natural gas, coal must be discovered and extracted before they can be conducive to mankind. This is a costly and time-consuming job. Meanwhile, the quantity of these fuels is limited. Therefore, it is proved that the global resources consumption is undue. Their supply is virtually unlimited…...

Flowering plants, like all living organisms, need a supply of food. They need it as a source of energy in respiration and they need it as raw material for growth and repair. Animals and most micro- organisms get their food in an organic form: they eat products from other organisms (such as fruit and eggs) or, nowadays, the organic substances made in laboratories and factories. Animals and the microorganisms that do this are called consumers. Due to the flowering plants…...

To investigate the ability of metals to act as a sacrificial protector of iron, preventing or reducing rusting. Theory Iron oxide is more stable than iron metal, so when given the opportunity iron will be readily oxidised. Iron reacts with oxygen and water to form a hydrated form of iron(III) oxide (Fe2O3i?? xH2O), known as rust, which is permeable to air and water so the metal underneath the rust layer continues to corrode. The iron atoms readily give away two…...

What has followed since has effectively been the refinement and proof of this…...

However, it is impossible for substances to be burnt under standard conditions. The enthalpies of combustion are different depending on the number of carbons and hydrogens in each substance.

When you woke up this morning were you hot? Or was your air conditioner on? How about your television? How did you get to school today? Physics controls all of these things. Physics is responsible for the electricity in our homes, which is something that is pretty well mandatory in this era. Physics provides the energy that powers everything from your phone to the lights in refrigerators, which is also pretty mandatory when it is dark. When you go up were you able to walk? Physics has everything to do from your muscles to how your foot pushes off the ground.

Physics also has control over maintaining our health. There is a branch of medical science that deals specifically with physics, medical physics. Every test and all your vitals are done with physics. The blood pressure cuff is a good example of a vital test that physics controls. X-rays, ultrasounds, defibrillator, radiation therapy for cancer, and laser eye therapy. Something as simple as your vitals is based on Physics.

Do you know how internet actually works? Physics has pretty much everything to do with it. Physics is how we communicate through devices like email, texting, calling, and social media. Fun fact, physics has a lot to do with the cables that that connect nations across the oceans. These cables are called Submarine Communication Cables, and there are about two hundred of them in existence. Their role is to connect the continents, except for Antarctica, and the core of the wire is made out of optical fibers. Without physics it wouldn’t be possible to call your neighbor, or even call overseas. Lots of families rely on the internet and phone to talk to relatives, some who may have moved, or even some in the military.

Since I wear contacts and glasses, I wanted to throw in a little segment about how physics helps you see when your eyes won’t. The way you see has a lot to do with physics, and as you know physics has a lot to do with light. An easy way to find out what kind of spectacle lens you need for nearsightedness, you must solve the equation: P=1/do+1/di=1/∞+1/−0.285 m, where 0.285 is the centimeters away from the eye (0.285 is input to show an example). An easy way to find out what kind of spectacle lens for farsightedness, you must solve the equation: P=1/do+1/di=1/0.235 m+1/−0.985 m away from the eye (-0.985 is an input to show an example). Laser vision for the eye is also to correct eyes by using physics.
