The role of Mathematics and Physics in Human life - 11

When leg is moving, kinetic energy is at maximum and potential energy is zero, but, when leg reaches nearest to belly or arc, potential energy reaches to its maximum

Role of Physics

Physics The Subject in we Deals with the Nature and it's phenomenon.Physics is one of the most important parts of the science as its principles are matter, force, energy, and motion. Whatever we do, there is physics involved. I thought there were uncountable things to write about physics. I realized I should write about the most used principle of physics and the activities. We use the principle of physics in our everyday life activities such as walking, cooking, cutting, watching, and opening and closing objects etc
Firstly, when we talk about Walking it involves numerous principles of physics. It does involve laws of inertia, friction, gravitational law, and Kinetic and Potential energy. When we take a step to walk, the leg plays a role of the axis and the stomach is in the motion of an arc. When we put our feet on the ground, we lay weight and pressure the ground. When the leg moves, kinetic energy is at its most and the potential energy is almost nothing or zero, however, when the leg is raised towards the stomach, the potential energy rises to its maximum. Number of principles of physics are involved in simple act of walking. It involves concepts of weight, Newton’s three laws of inertia, friction, gravitational law and potential and kinetic energy. When we walk, we actually act like an inverted pendulum. When we put the foot on ground, it becomes our axis and our mass is cantered in our abdomen, describing the shape of an arc. When we set foot on ground, we actually put weight i.e w=mg and apply backward force on ground, as the response to our weight, ground responds by an opposing force which is vertical in nature, on leg which slows us down and this slowing process continues unless our leg comes nearest to our tummy.
When leg is moving, kinetic energy 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 converted to kinetic energy and this process continues. We act as an imperfect pendulum, because all potential energy is not converted into kinetic energy. Only 65 percent of energy is provided by stored potential energy to take next step, remaining 35 percent is provided by bio chemical processes.)When we walk we actually do some work in physical terms, as W=F*S, when we exert some force and as a result of it we cover some distance we actually do work. During walking, Newton’s three laws of motion are applied. First law of motion states that, a body remains in state of rest unless a force is applied on it. When we are at rest, inertia is at maximum. Body needs largest amount of force to get out of state of inertia, i.e when we start walking. When we talk first step the energy is transferred from foot to upper body parts 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. Second law of motion states that a=F/m i.e acceleration is directly 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 reactionary vertical force on body
When we are doing Cooking ,There is use of Thermodynamics that branch of physics that deals with heat, temperature and work done due 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 pan, with water or something else in it, on burning stove the energy in flame of stove touches cold pan, it starts transferring heat to the pan thus making it hooter. This phenomenon is called conduction. Convection is a process of movement of molecules in liquid and gases. When we heat the pan, the water molecules on the base of pan start heating up, a time comes when 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. Similarly When we cut fruit and vegetable, we never realize that physics could be involved in this simple task, but, surely it is. In order to cut anything, we have to exert pressure on knife. When we increase the pressure we can cut an object easily. Pressure 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.
We should give more focus on the real part of Physics in our daily life .I will quote here the words of My Few Mentors like Dr Mohammad Farooq Rather Presently Principal at GDC Kupwara Whenever he teaches us He always says realize the Physics in daily life, realize it in your daily activities otherwise you will not get the same. Similarly Dr Mohammad Ashraf Shah Hod Physics NIT Srinagar always focus On The same thing how to realize the Physics in our daily life . He organised various programs under the banner of INSPIRE For the Students of Valley in order to aware the Students About the aspects of Physics in our daily life . Such type of programs will provides the Interest among the students about the subjects.
I think it will be better if we give the practical application of Physics in the daily life so that students will not feel it though. Our Schools should organised the Programing on the Importance of Physics in our daily life and make the students aware about the recent research aspects of physics.( Concluded)
