The science of physics is derived from old Greek wording ‘physis’ meaning ‘nature’. The science of physics contributes greatly to our daily lives provides an understanding of how our universe works. Physic can be defined as the study of motion and matter through space-time.
As everything in our surroundings and the universe is composed of matter, physics is an essential and integral part of everything we do in our daily lives.
In our modern-day world, physics has played a crucial part in developing new technologies.
Having a better understanding of nuclear physics and electromagnetism in the 21st century has aided in the development of the products that have transformed our daily lives.
Examples of such technological advancements include computers, television, house appliances, radio, and mobile phones. Physics plays an important part in our daily lives one way or another. Let’s observe ten examples of how physics helps in our everyday life as follows
- Act of Walking.
When you get ready for school or office, many of us have to walk most of the time as it is our primary form of commute up to certain distances.
The act of walking is because of the laws of physics. While you take a walk in the park or on a slippery road, we must maintain good grip due to our shoe’s contact with the road surface.
The certain contact is known as “traction” or “friction,” which contributes towards your grip while walking. If you face reduced friction like a wet road, you will fall.
- Ironing clothes through Steam Iron.
When you get ready for office in the morning, many of you need ironed clothes; therefore, the science of physics comes into play here. Using your steam iron home appliance uses the science and law of physics to make it work.
The main principle used by the steam iron appliances is “heat” which contributes towards thermodynamics in physics as heat is a form of energy that is transferred from warm iron to cold clothing through the heated base metal plate.
- Working of Alarm Clock.
Most of you experience physics without even noticing first thing in the morning when your personal alarm clock sounding alarm noise or buzzing wakes you from your sleep.
Sound waves are something you experience or hear but cannot see, which are contributed by the science of physics. The science of physics developed the Quantum mechanics theory concept by working on sound waves’ properties, propagation, and origin.
- Working of Seat Belts.
While traveling every day, you may have wondered how your seal belts work towards providing protection from car accidents. Physics comes into play here again by working on the physics “inertia” concept being the unwillingness of a certain body or object to change its state of motion or rest.
By using the concept of “inertia” your car seat belts prevent you from going in a certain direction as the body resists stopping due to physics inertia of motion.
- Working on a Ballpoint pen.
You might not even notice the working of your everyday use weapon in your daily life: the ballpoint pen. The science and law of physics contribute to the ballpoint pen’s working as you would not even be able to write anything without the laws of physics being gravity coming into play.
When you move your ballpoint pen across your paper, roll the ball, forcing the certain ink to drop towards the ball due to gravity to be transferred on the paper.
- Working of Mobile Phones.
Today, we are utilizing the modern applications of physics science without even realizing it: the development of mobile phones. In this age of digital technology, everyone has experienced its impact by getting the latest information, news updates, ordering groceries, or booking your online ticket through mobile phones.
Modern mobile phone technology works on the science and principles of the electromagnetic spectrum, magnetism, and the principle of electricity being developed by physics.
- Working of Earphones.
When you are bored, you wish to listen to some of your personal favorite music tracts. Have you ever wondered how the technology behind earphones or headphones works? Well, it’s the physics at work here again as physics concepts of sound waves and magnetism work together to make your headphones work.
When you connect your earphones to your mobile phone or mp3 player, the magnetism creates certain electromagnetic fields which produce sound waves that you hear.
- Working of Camera Lenses.
Many of you utilize your various digital cameras and mobile phone cameras to take your “Selfie” images every day without knowing its unique working underneath. There are special lenses present in various cameras that work on physics optics principles.
Using a complicated set of convex lenses set the scene and provides a certain mobile phone or camera with an image that is reflected outside of the camera.
- Working of Wifi
Many of us enjoy the modern technology of WIFI without acknowledging how it works. There are certain waves present in the air like sound waves or light which travel through various electric and magnetic fields. These special electromagnetic waves are invisible to us.
These waves have a special feature defined as wavelength, being the distance between peak waves towards the next. The various electromagnetic waves carry their signals but do cross or interfere with one another, which is their advantage.
This defines how physics contributes towards working radio or the internet (WIFI) and how we connect various electronic devices with one another.
- Working of Battery
Many of us utilize batteries every day for our cars, home appliances, toys, tv remotes, among others. These batteries function like an electricity bank and work on the physics concept of “capacitance”. Ever since the early 18th century, capacitors were utilized to store electricity.
Conclusion: So, whether we like it or not, the science of physics plays a vital role in our daily life towards the progression and advancement of our human civilization. Physics is not just limited to one certain field applicable to physics, but there are many comprising communications, transportation, energy, aviation, satellites, space, and modern technologies.
