Application of Physics in Daily Life

Physics in everyday life

Physics, or the study of matter, energy, and the interactions between them, helps us to understand the laws and rules that govern the physical world. Not every student will grow up and study physics on a deeper level, but everyone uses basic physics concepts to navigate everyday life.

How Everyone Uses Physics Concepts Every Day

Studying physics may sound overwhelming, but students are more than likely already very familiar with many of the concepts. Combatting a negative or frustrated attitude starts with giving students the examples and ideas that will help them to feel both interested and excited to learn about the “how” and “why” behind them.

1. 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

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 sole plate.

3. Walking

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 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

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. Car Seat-Belts

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 from moving in a forward direction; as your body  resists being stopped because of inertia of motion.
