How to Make Use of Real-life Applications to Learn Physics

Unless physics is your job, there’s a huge chance that you’ll never actually get to use what you learned in physics class or in A Level Physics tuition. However, observing is completely different to applying, and the latter is a very important skill for those who want to learn physics. Learning how to apply your knowledge is a skill covered by any physics tuition in Singapore, from O Level, A Level and ip physics tuition.

Below are a few examples of real-life applications of physics that happen around you every day, that should make it easier to understand the various concepts:

Cutting Food, Fruits and Vegetables

Who would have ever thought that something as mundane as cutting involves physics? To cut, we have to put pressure on the knife that we use. The more pressure we exert, the easier it’ll be for sure to cut an object. It also helps if we use a sharp knife. However, regardless of whether it’s blunt or sharp, applying the same amount of pressure doesn’t always work, because we have to consider the force, the area directly under on the force we apply, as well as many other considerations you would have learned about in class.

Breathing

The very fact that you’re alive and breathing is one of the most wonderful applications of physics. According to Boyle’s Law, pressure and volume of a gas always have an inverse relationship. When we inhale, the resulting expansion of our chest leads to an increase in value and a lower pressure inside the lungs compared to the surrounding atmosphere. The opposite then happens whenever we exhale.

Another neat application of physics in breathing is when the oxygen in the air diffuses into our blood. At the same time, CO2 is also expelled from our body.

Circulatory System

Again, we’ve got another application of Boyle’s Law. Whenever our heart muscles contract, it reduces the volume inside it. It causes high pressure in the region, forcing the blood out into the arteries.

Meanwhile, if the heart is relaxed, there’s a higher volume, which produces a low-pressure area that basically sucks in blood from the veins. Just imagine that happening to your heart, with 4 such chambers and valve mechanisms working round the clock to pump blood throughout our body.

That’s just the start. There are also the fluid mechanics related to the mechanics of the muscles, the blood flow, and many more.

Walking

According to Newton’s Third Law, for every action, there has to be an equal and opposite reaction. That very law applies to walking. How? Because whenever you put your feet on the ground, you apply force to it. In return, the ground also applies force to your foot in the opposite direction, which helps push you forward.

Such real-life applications are very important when trying to learn physics. O level Physics Tuition in Singapore are filled with such lessons that help students gain a better and much deeper understanding of physics, as well as how it applies to the world around us.
