physics in our daily life essay

Physics  extends to your  daily life  to describe the motion, forces, and energy of the ordinary experience. Physics is at work in tasks such as walking, driving a car or using a phone. Knowledge of physics is helpful in everyday situations as well as in non-scientific tasks.

For example, physics helps you understand:

  • How food is cooked in a microwave oven,
  • Why a radiator helps to dissipate the heat of a car engine, and
  • Why a white ceiling helps to keep the inside of a house cool.

Thousands of such questions can be answered and explained via physics.

Physics is the foundation of many critical scientific disciplines, such as chemistry is rooted in quantum physics which describes the in-depth study of atoms and molecules. Physics is also applicable in most branches of engineering. In architecture, physics is pivotal to determining structural stability, acoustics, heating, lighting and cooling systems for buildings. In Geology, the study of non-living parts of the Earth, such as the study of atmosphere, lithosphere, hydrosphere, earthquakes, storms, volcanoes, and other natural disasters, such as floods, droughts, and extreme heat on the Earth’s surface. Some disciplines, such as chemical electrodynamics, optics, thermodynamics and modern physics, are important branches of physics for studying natural phenomena.  Physical science  also describes the chemical processes in the human body through biophysics. Physics is implicated in medical diagnoses, such as X-rays, magnetic resonance imaging (MRI), and ultrasonic blood flow measurements. Physics can also explain what we perceive with our senses, such as how the ear detects sound or how the eye detects colour.

10 Examples of Physics in daily life:

1. alarm clock ringing:.

Physics is involved everywhere in your daily life, from when you wake up in the morning to going to sleep at night. The alarm clock’s buzz helps you wake up in the morning according to your schedule. Sound is something that you cannot see but can hear or feel. Physics studies the origin, transmission, and properties of sound. The  concept of quantum mechanics  is applicable here.

2. Electricity: 

Electricity is one of physics’ most important direct applications in people’s lives and a major energy source. It is a continuous stream of  electric charges moving inside a conductor , known as electric current.

The importance of electricity can be understood from the conditions people endure when electricity is disconnected from their houses. All the electrical appliances stop working, the lights go out, and life becomes difficult.

3. Static Electricity:

When two objects that are not good conductors of electricity are rubbed together, electrons from one object rub off on the other.  The more friction between two objects, the more static electricity is built up  and the greater the electric charge.

This is why when you rub the pencil on your hair and move it towards small pieces of paper, the small pieces stick to your pencil. This is just a small example.

4. The Density of Seawater and Swimming in it:

The density of seawater is higher than normal water, so it is easier to swim in it. There’s an ocean in which people never drown and remain above the surface of the water because of its  water’s density . The name of this sea is the dead sea.

5. Smartphone: 

Smartphones have become like oxygen in modern social life. Now hardly anyone will be untouched by the effects of smartphones. Whether it is to send an important message, chat constantly, talk on video calls, send money or do any other important work, smartphones are everywhere. But do you know how smart phone works?  It works on the principle of electricity and the electromagnetic spectrum , the wavy patterns of electricity and magnetism.

6. The Science behind opening the Doors:

If you apply force near the door hinge, the door will not open because it will not be able to rotate around the hinge. But, when you apply the same force away from the hinge, the torque will be larger. That makes you  easily open the door  without exerting more effort.

7. How does the Washing Machine dry the Clothes?

The dryer of a washing machine is a rapidly rotating container that applies  centrifugal force  to its contents. Centrifugal force acts away from the centre. It throws water molecules radially outward on the fabric during the washing machine’s spin cycle.

8. Why are cars facilitated with Seat belts & Airbags?

When the brakes are applied on a moving car, the lower parts of the vehicle and the passengers attached to the car stop immediately, but their upper parts tend to fall forward due to  inertia . This is why airbags are also installed in cars, along with seat belts.

9. Falling Incident:

Suppose you are climbing a tree, and suddenly, you slip and fall from the tree. Then, you are sure to break a bone or two. But if the same thing happens with a small ant, i.e. if the ant falls below the height, it does not get hurt. Why is this?

From the ant’s perspective, the atmosphere is dense and viscous, and its experience of falling from a height is similar to that of us falling through the water to the bottom of a pool. The air beneath the falling becomes a large cushion of protection.

10. How does a Pen write?

Whether at your workplace or school, the ballpoint pen is your weapon. If there were no physics, you would hardly be able to write on paper with a ballpoint pen. Here the  concept of gravity  comes into play. As your pen moves over the paper, the ball turns, and gravity forces the ink down onto the top of the ball, from where the ink continues to transfer to the paper.

It is hard to imagine life without physics. Many other examples are available; you only need an eye to spot them. If you have any queries or suggestions, kindly let us know in the comments section below.
