Importance of Physics in our Daily Life Essay

importance of natural philosophy in our Daily Life EssayRole of physical science in our nonchalant lifespanINTRODUCTIONWe are living in the century of science and technology and introduction of science in our daily has transformed our lives. When people had no idea about science, even thus their lives were governed by principles of different branches of science. When we calorie-free a fire, it is a chemical offset when we eat and digest food, it is biological process when we walk on Erath, it is governed by laws of physics when an Earthquake occurs, its a seismic portrayalivity when we let loose about different terrains and gems of Earth surface, it is related to Geology. There is no star activity of our lives, which define our one or other field of science. Similarly, physics governs our everyday lives and is involved in a number of activities we perform and things we consumption in our daily life. Here we testament address how physics is acting its part in running o ur everyday tasks and assists us to do our errands, chores and duties smoothly and effectively.BODY natural philosophy is considered natural science because it deals with the things like matter, troops, vigour and question. As these completely are related to task related to everyday life, so, we abide say that physics studies how the universe working, how Earth Moves most the sun, how alightening strikes, how our refrigerator works and many more. In short, physics define how everything works around us. When bumnot separate anything from science and, our world cannot disconnect itself from the wonders of Physics. When we look around us, we can see a number of things that work on the principles of Physics. We can justify our several activities by fashioning use of the knowledge of Physics. Here, we will discuss some of the example, which will help us to record how physics is playing its part in our lives each day. passA number of principles of physics are involved in ro und-eyed act of walking. It involves concepts of weight, Newtons three laws of inertia, friction, gravitational law and potential and kinetic dexterity. When we walk, we real act like an inverted pendulum. When we put the foot on ground, it becomes our axis and our great deal is centered in our abdomen, describing the shape of an arc. When we set foot on ground, we real put weight i.e w=mg and apply backward extort on ground, as the response to our weight, ground responds by an opposing array which is vertical in nature, on leg which slows us down and this retardent process continues un slight(prenominal) our leg comes nearest to our tummy. When leg is moving, kinetic push is at maximum and potential energy is zero, but, when leg reaches nearest to belly or arc, potential energy reaches to its maximum. When another step is taken, the stored potential energy is born-again to kinetic energy and this process continues. We act as an imperfect pendulum, because all potential ene rgy is not converted into kinetic energy. Only 65 percent of energy is provided by stored potential energy to take following step, remaining 35 percent is provided by bio chemical processes. (Kunzig, 2001)When we walk we actually do some work in physical terms, as W=F*S, when we conserve some force and as a go forth of it we cover some distance we actually do work. During walking, Newtons three laws of motion are applied. First law of motion states that, a soundbox remains in state of rest unless a force is applied on it. When we are at rest, inertia is at maximum. physical structure needs largest amount of force to get out of state of inertia, i.e when we cacography walking. When we talk first step the energy is transferred from foot to upper body part and we start moving, during the process of walking inertia keeps on changing increases when we set foot on ground and decreases when we move the foot up. bet on law of motion states that a=F/m i.e quickening is at one tim e proportional to the force we use or exert while walking, therefore, when we will apply more force, our acceleration will increase. Third law of motion is about action and reaction, when we set foot on ground we exert force on it and as a result to it ground exerts reactionist vertical force on body. (Patricia Ann Kramer, 2011)CookingThermodynamics is a branch of physics that deals with fondness, temperature and work done overdue to it. Heat is a form of energy that can be transferred from one medium to another i.e heat transfer. For heat transfer, heat travels from hotter surface to cooler. When we put goat god, with peeing or something else in it, on burning stove the energy in flame of stove touches glacial pan, it starts transferring heat to the pan thus making it hooter. This phenomenon is called conduction. Convection is a process of drive of molecules in liquid and gases. When we heat the pan, the irrigate molecules on the base of pan start heating up, a time comes w hen they get enough energy and become hotter than the molecules around them, then they start moving to the surface of water. The water molecules on the surface are cooler and heavier from hot water, due to less heat energy, thus start moving down, this process continues until all water comes at same temperature. (ouchmath, 2011)The cooking process is an open system, because in this both(prenominal) matter and energy is lost. According to zeroth law of thermodynamics energy should be conserved, in our case the energy lost by flame is use by pot to heat water and thus the total energy remains conserved. If we use force per unit area cooker it uses het energy to bring self-produced changes into food by using kinetic energy of molecules to bring chemical changes in food thus satisfying law of thermodynamics that spontaneous works are done due to work energy. (Lathbridge, 2013)Cutting results and vegetablesWhen we sew fruit and vegetable, we never realize that physics could be invol ved in this simple task, but, surely it is. In order to stretch anything, we have to exert pressure on glossa. When we increase the pressure we can cut an object comfortably. mechanical press is dependent on force and area i.e directly dependent on force and inversely dependent on area. In simple terms we can say that when we exert more force we can cut an object easily, but, if same force is applied with a knife with thicker edges, we cannot it. From experiences we learn that the knives which have edges with smaller surface area can help to cut an object easily. Similarly, we can cut easily with a sharper knife than blunt. The blunt knife offers more friction, due to its rough edges thus making it difficult to cut an object. throwingOur look are an incredible impart by God. We see wonders of the world, by this small organ. When we talk about parts of body and their function, it is the general concept that we are talking about biology. But, we flatten the fact that functions of our body parts are alike working chthonic the laws of physics and chemistry. If we talk about the sense of seeing, we come to know that our eyes work as a camera to see things around us. The crystalline lens in our eyes is convex i.e it converges or centeringes light. When light enters our eye, cornea and lens focus the light. Iris controls the amount of light entering the eye and iris creates an scene on retina, which is real and inverted i.e like in camera. The image of light is converted into electrical signal, by photoreceptors, and sent to vision centre of champion by optic nerve. The vision center analyses the electric signal and arranges it into its lord form i.e to be seen by eye. The image we can see is due to the amount of light radiateed from that object. This is the reason why we cannot see in dark. (Edmondson, 2005) plaza can perceive different shapes and colors of the objects. Light consists of seven colors, when it fall on an object say, book of color red, it absorbs all the colors and reflect red color. This helps us to interpret that the cover of this book is red. When light falls a ovalbumin object then it reflects all the colors and thats why it seems white (we also regard light as white light). Similarly, when light falls on black object it absorbs all the light and reflects nothing thats why that object looks black. (Pappas, 2010) arising and closing thresholdsPhysics is also involved in opening and closing of hinged doors. The phenomenon involved in opening and closing of door is torque. contortion is the force required to bend an object about an axis or fulcrum. When we open a door by using the handle, at farthest place from hinge, we can easily open the door by producing torque, =F*l sin , where l is the distance of hinge from door hirer or handle. (Lesson 27a crookedness (AP Only) , 2013)If the knob is located near the hinge, we have to exert more torque, thus producing less angular acceleration. When we apply force perpendicular to the door, larger angular acceleration is produced. When we apply force on the door knob, compel the door to short-circuit on its axis thus acting on the principle of torque. Torque is positive when we open the door clockwise and negative if we open it anticlockwise. (Broholom, 1997) purposeHere, we have seen a limited example of physics, but over life is governed by this branch of science. Physics governs a lot of natural phenomenon and also define a number of man made things like cars, refrigerators, cook and escalators. Hence, we can say that our world is ruled by physics.Works CitedBroholom, C. (1997, October 20). Opening a door.
