The Applications of Physics in Real Life
Explain the applications of physics in real life
Discoveries in Physics have led to various inventions that influence our lives.
  1. At home: All tools and machinery that we use in our homes to make work easier are made in accordance with the laws of Physics. They include hoes, hammers, door handles, knives, spoons, hinges, car jack, pulleys, tillage implements, and so many other things. For example, it would be difficult for us to try to lift a car so as to change its tires. However, using a car jack makes this task easy. Electrical appliances such as a cooker, hot iron, heater, electric lamps, washing machines and so on are a result of the application of the knowledge of Physics.
  2. Medical field: A variety of medical processes and machinery rely on the application of the knowledge of Physics. Some of these machines are used in diagnosis and treatment of various ailments as well as sustaining the lives of patients through certain forms of therapy. Examples of machines used in hospitals include laser, X-ray, incubators, ultrasound and infrared machines. The knowledge used in handling and even actual use of these machines is based on the knowledge and skills acquired in Physics.
  3. Source of energy: Some processes and machines help us obtain energy for our daily use. These machines make use of various laws of Physics to give us different forms of energy. For example, batteries and generators provide electrical energy that is readily used in radios and televisions. A car battery provides energy needed to drive a car. When devices like bulbs are connected to these sources, they provide light energy for daily use.
  4. Transport: Application of laws of Physics governing concepts such as friction and frictional forces ensures that human beings and animals can walk, run and stop without falling over. Vessels used in transportation such as cars, ships, aeroplanes and trains are also able to move, brake and stop when necessary. This is all because the laws related to friction, flotation and balance are observed and applied accordingly. When these laws are disobeyed, ships sink and trains derail.
  5. Communication: Devices used in communication systems such as telephones, modems for accessing the internet and television, use cables, telecommunication transmitters and receivers to relay information. The knowledge of Physics is essential, because these instruments make use of fiber optics and radio waves in order to relay messages. Newspapers, letters, electronic mails (email), fax massages from fax machines and short messages (SMS) through mobile phones are reliable means of communication. All these things require the knowledge of Physics.
  6. Entertainment: Physics enables people to enjoy a variety of leisure activities as is evident in photography, digital appliances, exercise machines and other sports equipment.
  7. Industry: Physicists have been able to come up with tools and process that have resulted in advanced technological equipment and new discoveries. These include highly accurate skills such as computer assembly and computer programs used in design, and instruments like binoculars and telescopes. The ability to land on the moon and measure the temperature of bodies are a few examples.
  8. In schools: The instruments and apparatus used in school laboratories are made through the application of the knowledge and skill acquired in a Physics class. These apparatus have to meet certain specifications or standards that are universally accepted.
Physics in Our Daily Life
Apply physics in daily life
Each of us applies Physics in our day to day activities.
Having an understanding of Physics may also help an individual to lift something heavy. For example, by using a simple machine such as an inclined plane or a lever, an individual can make the load easier to lift. Physicists study simple machines extensively and use the lessons they learn to make increasingly efficient tools.
It is not easy to walk on a slippery floor unless we wear shoes made with a rough sole.
To stay warm in the winter, people up turn the heat up or use the principles of physics to understand how to make better use of the heat that is already in their homes. Heat flows via conductive, radiant and convective means. Understanding the differences between the three forms will allow an individual to insulate a house better. For example, by using ceiling fans intelligently, someone can make the convective heat flow in a house work to their advantage.
A car driver must be aware of the forces around him in order to keep the car in position when moving and to avoid overturning when moving around corners.
A football player knows that for a ball to go at a far point he must kick it with an extra force so that it absorbs enough energy.
A cook knows that he/she must use a sharp knife when cutting a piece of meat so as to avoid application of greater force.
A person swimming has to displace a large volume of water so as to continue floating.
Therefore, in one way or another, Physics is essential in our daily life.
