INTRODUCTIONWe are living in the era of science and technology, and the inclusion of science and technology in our everyday life has greatly improved our lives. When individuals had no notion about the science after then their lives were ruled by the values of many branches of science. While we light the fire,  a chemical process takes place; while we take food and digest it, it is biological based process; when we use to walked on ground, it is directed by the universal laws of physics; when an Earth-quake happens, it’s a seismic action; while we talked around many lands and gems of the surface of Earth surface, it is linked to Geology. There is not a single action of our everyday lives, which defines our one or other arena of science. Likewise, physics rules our daily lives and is elaborate in many actions that we perform and things we that we used in our everyday life. In this paper, we will deliberate how physics plays an important role in running our daily jobs and supports us to do our chores, errands, and obligations easily and efficiently.BODYPhysics is deliberated as a natural science as it compacts with the elements like substance, energy motion, and force. As all of these are linked to duty associated with daily life, hence, we could say that physics deals how the cosmos, universe, and earth worked, how the planet Earth moves round sun, how lightning strikes the earth, how our fridge works and much more. In brief, physics describe how the whole thing works nearby us. When we could not find distinct, everything from the science and, our world could not detach itself from the miracles of Physics. When we see around us, we could see several elements that work on the philosophies of Physics. We could enlighten our numerous actions by making the usage of the information of Physics. Here, we would deliberate certain instance, which would assist us to study how physics is playing an important role in our lives every day(Kumahara, Tanaka, & Schutz, 2004).WalkingMany Principles of physics are elaborated in simple action of walking. It includes the notions of mass, Newton’s 3rd laws of motion, gravitational law, friction, kinetic and potential energy. When we use to have a walk, we basically act like an overturned pendulum. When we placed the foot on the ground, it turns out to be our axis, and our weight is pinpointed in our abdomen, relating the figure of an arc. While we set up our foots on the earth, we basically put the weight that is w=mg and applies a retrograded energy on the ground, as the reply to our mass, the earth retorts by an opposite force which is perpendicular in nature, on the leg which decelerates us and this decelerating method endures until our leg comes adjacent to our tummy. While the leg is stirring, K.E (kinetic energy) is at the extreme, and P.E (potential energy) is at zero value, however, when leg extends close to the arc or belly, the P.E (potential energy) reach to its extreme values. When the further step is engaged, the store P.E (potential energy) is transformed to the K.E (kinetic energy), and this procedure carries on. We act as an im-perfect pendulum, as all of the P.E (potential energy) is not transformed into the K.E (kinetic energy). Only 65% of the power is delivered by the stored P.E to takes to the further next step, while the remaining 35% of the energy is delivered by the biochemical procedures(Hunt & Minstrell, 1994).While we used to walk we are doing certain work in term of physics, since W=F*S, when we exert certain forces and as a consequent of it, we cover certain distances we do some work. While walking, the 3rd law of motion of Newton is applied. The 1st law of motion deliberates that that, an object continues to remain in the state of rest or motion until an external force is exerted on it. While we are the rest position, inertia is at an extreme value. The object requires a large quantity of power to come out from the state of inertia that is when we start to walk. While we take the 1st stage the power is transmitted from our foot to upper part of the body and we start to move, in this procedure of walking, the inertia retains on varying upsurges when we put the foot on the ground and reduces when we moved the foot in the up direction. Newton’s 2nd law of motion deliberates that a=F/m(a stands for acceleration, F for force and m for mass) that is acceleration has a direct relationship with the force that we used or exerts while we are walking, hence if we apply further force, our acceleration will also increase. Newton’s 3rd law of motion is the action and reaction of the object; It states that every action has an equal and opposite reaction.CookingThermodynamics is a branch of physics that deals with temperature, heat and amount of work that is completely due to it. Hotness or heat is a type of energy that could be moved from one medium to another medium. That is the transfer of heat. For heat-transfer, heat moves from the hotter-surface to colder surface. When we place the pan, with liquid or anything new in it, on the red-hot cooktop the energy in the flame of the stove traces the cold-pan, it starts to transfer the heat to the pan, and therefore it makes it more hooter. This process is known as conduction. Convection is a method of motion of particles in a liquid state and the gases state. While we heat up the pot, the molecules on the base of the pan start to heat-up, after a while when the molecules have sufficient energy and turn out to be more and hotter than the particles nearby they start to move toward the surface of the water. These molecules of water that comes to the surface are cooler and weightier as compare to that of hot water, because of the lesser heat-energy, hence it starts moving downwards, this procedure lasts till all of the water molecules reaches at the similar temperature(“Role of Physics in our daily,” n.d.).The cooking method is an open-system, as in this together with the mass and the energy is loosed. Zeroth law of thermodynamics says that energy must be preserved, in our circumstance the energy is loosed by the flame is being used by the pot to heat the water and therefore the sum of energy continue to be preserved. If we use the pressure oven it usages the heat-energy to carry impulsive variations into the food with the help of K.E of the particles to carry chemical variations in food items; therefore sustaining the laws of thermodynamics that impulsive works are finished because of the work-energy.Cutting vegetables and fruits When we cut vegetable and fruit, we certainly not understand that the physics can be included in this modest job, then, certainly it is. To cut vegetable, fruits or whatever, we must apply force on the knife. When we rise the force we could cut a fruit or vegetable simply. Force is reliant on pressure and area that has a direct relation between force and inversely relation with the area. In short, we could say that when we apply further force, we could cut any object simply; however, if the similar force is being executed with the help of a knife with thicker edges, we could not do it. From these practices, we have learned that the knife which has the edges with the smaller surface-area could assist to cut any object simply. Likewise, we could cut simply with a knife that has Sharpe edges than that of blunt. The blunt shaped knife has more resistance or friction, which is because of its uneven edges and hence makes it harder to cut any item(Kumahara et al., 2004).Closing and Opening of doorsPhysics is also applied in the closing and opening of the hinged gates or doors. The method involves in the closing and opening of the door is known as torque. Torque is defined as the force that is required to twist anybody around an axis or fulcrum. When we open a gate or door with the help of handle, at furthest place from the hinge, we could easily open the gate by making the torque.CONCLUSIONHere, we have observed a limited instance of physics; however, our lives are ruled by physics and other branches of science. Physics rules several natural actions and also describes a variety of human-made items like vehicles, fridges, escalators, and microwave. Therefore, we could say that the physics and Physics govern our lives is making our life easy and modifying our way of life ReferencesHunt, E., & Minstrell, J. (1994).
