What is Physics?
The Meaning and Importance

During the seventeenth century, the modern science of physics started to emerge and become a widespread tool used around the world. Many prominent people contributed to the build up of this fascinating field and managed to generally define it as the science of matter and energy and their interactions. However, as we know, physics is much more than that. It explains the world around us in every form imaginable. The study of physics is a fundamental science that helps the advancing knowledge of the natural world, technology and aids in the other sciences and in our economy. Without the field of physics, the world today would be a complete mystery, everything would be different because of the significance physics has on our life as individuals and as a society.
In the natural world, physicists find new discoveries constantly. Some of these discoveries include the study of motion and forces. The well-known scientist, Isaac Newton, came up with the three laws of motion, which state rules and facts about the movement of an object. Our textbook states the laws of motion, as ?A body in motion will remain in motion at a constant speed and direction unless an outside force acts upon it. The net force acting upon an object is directly related to the mass and acceleration of the object resulting acceleration is in the direction of the net force, which is the vector sum of all forces acting upon the object. Finally, the third law of motion states that when one object applies a force to another, the other object applies the same amount of force back to the first object, but in opposite directions.? With these laws of motion, we can understand in detail how our world works. Also, that the movement of an object is more complex than a simple push. This discovery is taught to students all over the world because of its great importance and will continue to enhance the knowledge of the mystery of our earth.
The importance of physics not only lies in the discoveries of the natural world, but in the technology in our modern lives. Today we use many gadgets in our everyday tasks, which act as convenient aids to all of our needs. Some of these little novelties are cell phones, radios, computers, lasers used in eye surgery, fiber optics used in phone lines, calculators, hearing aids, and even global positioning systems.

Essay on The Mirrors of Classic Physics - The Mirrors of Classic Physics Plenty of conceptions of mirrors are not so different from models in middle school physics. The mirror is a line dividing the ‘real’ from the ‘virtual’, and the image is the same on both sides. It is a plane in three-dimensional space, a slash in textual space, and a boundary to fluid spaces. In physics class, rays of light go from each point of the image and bounce off the mirror in such a way that they seem to have come from the virtual object. These are not the only mirrors....   [tags: Physics Science Self Identification Essays]

The Importance of Play in the Education System Essay - Changes in the Education System The focus of the education system has changed drastically in the past twenty-six years. Approximately forty percent of elementary schools have already removed or reduced recess time, or are in the process of doing so, in comparison to the ten percent reported in 1989 (“Recess and the Importance of Play” , n.d.). Not only is recess important, but all types of play have been demonstrated to be beneficial to school aged children. Play is essential to healthy development encompassing mental, emotional, and physical well-being in all children....   [tags: education, stages of play]

The Physics of the Arc Essay - ABSTRACT Several researchers have devoted efforts on studying physics of arc and descriptive models are used to explain many arc welding related phenomena. However, due to the subject complexity, doubts still emerge about the mechanisms of some phenomena related to the arc. For instance, the description about electromagnetic interactions with the arc, which governs the arc trajectory and lead to plasma jet and arc blow formation, seems to be yet controversial. Thus, the present study aimed a better understanding of these phenomena....   [tags: Physics ]

Essay about Finding the Meaning of Life - "Students in our best universities do not believe in anything, and those universities are doing nothing about it..." -- Allan Bloom The function of the university, according to Bloom, is to remind students of the importance and urgency of the question, and to give them the means to pursue it. Instead, universities teach us that there is no absolute right or wrong, no just and unjust. There are no absolute answers in today’s society. Rather, everything is relative; relative to culture, to religion, to geography, and to time....   [tags: Meaning of Life, 2015] 694 words

The Physics of Bicycles Essay - The Physics of Bicycles 1 Spokes Even the earliest bicycles used spokes of one sort or another. In fact, even in ancient times many chariots and animal-drawn carts used spokes. A spoked wheel can be made as strong as a solid one and have only a fraction of the weight.While early spoked wheels were almost always made out of wood, the bicycle wheels and spokes of today are made out steel or aluminum or occasionally more exotic materials such as carbon composite or ceramics....   [tags: physics bicycle bike cycle] 814 words

Essay about Physics of Semiconductors - Semiconductors were being studied in laboratories as early as the 1830's. The materials were usually poor conductors if heated and often carried photoelectric properties. (Electrical production by shining light on the material.) Soon, this property of changing conductivity would become of vital importance to the world of electronics and communications. (Micron) Common semiconductors include silicon, zinc and germanium; however, silicon is by far the most widely implemented due to its abundance. Also, its reasonable speed, simple processing, and useful temperature range make it a good choice among other semiconductors....   [tags: physics conductor semiconductor] 853 words

Physics of Soccer Essay - Physics of the Ball How and where you kick the ball is the most important aspect within the game of soccer. Lets say you kick the ball perfectly giving it no rotation (or spin), this means that you have given the ball a velocity (v) and an initial angular speed of zero. When the ball comes into contact with the ground it will begin to spin because the ground is not frictionless. The soccer ball will eventually begin to roll without slipping, which is when the balls center of mass is equal to its angular speed....   [tags: physics sport sports soccer football] 1400 words

These forms of technology were created and invented using the science of physics. Without these novelties in our lives, things would be extremely different. How would we communicate from long distances, or how would we solve complex problems in our math and science classes? Technology in my opinion involves the most important discoveries known within the last century thanks to the physicists and their studies.
The field of physics plays a large role in other sciences and in our economy. The general ?science? includes many fields such as biology and chemistry. The truth is, without physics, the other sciences would not have a starting base to stand and grow on. Physics is used as a tool in all of the other sciences and is a building block to the educational backgrounds of a scientist. Physics even includes the basic laboratory skills needed in other forms of science and medical research. The reason why physics is essential to our everyday life is its importance to the economy. The study of physics has brought numerous new inventions and discoveries. For this reason, an increase in money has landed in the United States that has dramatically helped our economy in the past century. Also, because it has landed new research and is discovering new fields of industry in order to save our country?s money.
The study of physics is much more than solving tedious equations, it is a combination of the study of matter and energy and their interactions. Physics can even go to a further extent involving the discoveries of the natural world, technology and the importance it holds for other sciences and our economy. The field of physics is indeed a variety of concepts used in a classroom as well as concepts used in our modern lives and society. Without physics, the world today would be extremely different and would be a complete mystery of all that surrounds us.
