10 Examples Of Physics In Everyday Life

Sponsored

On this “Living Planet” that we call Earth, there are lots of interesting events that take place. These events are around us, which we see or do or experience regularly. At some point in time, your curiosity would have pushed you to ask questions about what’s going on? How does that happen? Well, leaving miracles apart, the answer to all these questions is “Physics.” In fact, Physics governs our everyday lives in one way or the other. Let’s have ten examples of Physics in everyday life:

Physics in Everyday Life

1. Alarm Clock

Physics And Alarm Clock

Physics gets involved in your daily life right from you wake up in the morning. The buzzing sound of an alarm clock helps you wake up in the morning as per your schedule. The sound is something that you can’t see, but hear or experience. Physics studies the origin, propagation, and properties of sound. It works on the concept of Quantum Mechanics.

2. Steam Iron

Steam Iron And Physics

Right after you wake up in the morning and start preparing for your school/office, you need an ironed cloth, and that’s where Physics comes into play. The steam iron is such a machine that uses a lot of Physics to make it go. The foremost principle of Physics used in the steam iron is “Heat.” Heat, in Thermodynamics, is a type of energy transfer from a warmer substance to a colder one. Ironing works by having a heated metal base- the soleplate.

3. Walking

Walking And Physics

Now, when you get ready for your office/school, whatever medium of commutation is, you certainly have to walk up to a certain distance. You can easily walk is just because of the Physics. While you have a walk in a park or on a tar road, you have a good grip without slipping because of a sort of roughness or resistance between the soles of your shoes and the surface of the road. This resistance, which is responsible for the grip, is called “Friction” or “Traction.” However, when a banana peel comes under your foot, you suddenly fall. Now, what makes you fall? Well, it’s due to the reduced friction between your shoes and the surface of the road because of the slippery banana peel.

4. Ball Point Pen

Ball Point Pen And Physics

Whether you are at your workplace or in your school, a Ball Point Pen is your weapon. Had Physics not been there, you would not have able to write with a Ball Point Pen on a paper. In this case, the concept of gravity comes into play. As your pen moves across the paper, the ball turns and gravity forces the ink down onto the top of the ball where it is transferred onto the paper.

5. Headphones/Earphones

Headphones And Physics

When you get tired of work or studies, listening to music comes handy. Have you ever thought how does your headphone/earphone work? Well, it’s again because of the Physics. The concept of magnetism and sound waves are involved in the science of your headphone/earphone. When you plug your headphone/earphone into an electrical source, the magnet in your headphone/earphone creates an electromagnetic field, which ultimately results in sound waves.

6. Car Seat-Belts

Car Seat Belts And Physics

Have you ever noticed that on which principle does your car seat-belt work? Well, it’s again Physics. When you tighten your car seat-belt, it works on the concept of “Inertia.” Inertia is unwillingness or laziness of a body to change its state of rest or motion. In case of a car collision, your seat-belt helps prevent your body moving in a forward direction; as your body resists being stopped because of inertia of motion.

7. Camera Lens

Camera Lens And Physics

The phenomenon of “Selfie” has engulfed people of every age groups. You entertain yourself by clicking photos. The Lens used in a camera works on the principle of Optics. The set of convex lenses provide the camera an image outside of the camera.

8. Cell Phones

Cell Phones And Physics

Cellphones have become like the Oxygen gas in the modern social life. Hardly, anyone would have been untouched by the effects of a cell phone. Whether conveying any urgent message or doing incessant gossips, cellphones are everywhere. But do you know how does a cell phone work? It works on the principle of electricity and the electromagnetic spectrum, undulating patterns of electricity and magnetism.

9. Batteries

Batteries And Physics

Whether in cellphones, cars, torches, toys, or any other appliance, batteries act as saviors of electricity. Batteries work on the principle of capacitance. Since the late 18th century, capacitors have been used to store electrical energy. Benjamin Franklin was the first to coin the phrase “battery” for a series of capacitors in an energy store application.

10. Doppler Radar

Batteries And Physics

To check the overspeeding vehicles, police often use Doppler Radars. Doppler Radars work on the principle of Doppler Effect. The Doppler Effect is nothing but a change in the pitch of a sound when the source of the sound is moving relative to the listener. It is because the frequency of the sound wave changes as the source of sound moves closer to or farther from the listener.
