Physics is the study of energy and matter, and how they relate to one another. It explains how the energy can be changed from one form to the other form.Everything surrounding us uses energy in one or other way. We can find Physics as the backbone for any daily life example such as, computers need wifi connections and electrical sources to work; planes, automobiles and trains use fuel to function; mobile and other telecommunication devices work on cellular signals. We can’t deny the fact that physics can be the solution to almost every problem that will occur in the future. Our dependability on physics has increased to such an extent that we can not imagine our life without it. Let’s discuss about the importance and need of physics in our daily life, how it has enhanced our lifestyle and made our everyday tasks easier than ever.

  • Thermodynamics: Thermodynamics is the branch of physics that is concerned with the temperature, heat and the work done due to it.

            Example in daily life: All the refrigerators, deep freezers, all types of air-conditioning systems.

  • Newton’s Laws of Motion: All the 3 laws of Newton’s Laws of motion are directly applied in our daily life.
  1. Newtons First Law of Motion: It states that, an object maintains a constant velocity unless acted upon by another force.

Example in daily life is, when we work against a batter for making a cake, the batter is at rest until an unbalanced force, the spoon acts upon it.

  1. Newton’s Second Law of Motion: It states that, Acceleration increases with force and decreases with mass.

Example in everyday life is, it is easier to push an empty box than a full one. If both the boxes are pushed with the same amount of force, then the empty one will go farther and the full one will be harder to stop.

  1. Newton’s Second Law of Motion: It states that, for every action force there is an equal and opposite reaction force.

Example in daily life is, When you are walking, you are actually pushing the earth and the earth pushes you back and this causes you to move. The same thing happens in case of cars, bicycles, and boats.

  • X-rays: X-rays are a type of radiation called electromagnetic waves.

            Example in everyday life: An X-ray is a common imaging test that’s been used for decades to help doctors to view the inside of a human body without having to make an incision. This can help them diagnose, monitor, and treat many medical conditions.

  • Pressure: It is a way of measuring how much force is acting over on area.

            Example in daily life: The ink dropper that we use almost on a daily basis actually works on the air pressure principle.  As soon we create a low pressure by removing the air inside the bulb, the ink flows in to fill in the void.

  • Torque: Torque is the application of force where there is rotational motion. Example in daily life: The torque used when opening a bottle cap, rotating force when turning the steering wheel.

Hence, physics has a great impact on our everyday life and enhancing the way we used to live before.
