Most people tend to associate Physics with famous people like Abraham Maslow or Einstein. For students, some may be able to find a relation between the concepts they learn in Physics and their everyday lives. Today’s physics classrooms have been made to focus too much on the theory and not enough emphasis is put on the practical side of life. Some may see the importance of learning the subject because they have no idea on how to apply it in life. Simple Below, I will share a few examples on how Physics affects your everyday life. You may have experienced some without knowing that it was indeed Physics playing that role.
Whenever you are walking or running from one point to the other, you normally have a good grip of yourself and the chances of slipping are minimal. This is because there is a certain resistance between your shoes and the surface you are walking on. That resistance that enables you to maintain your grip is called friction. If something slippery were to come in contact between your shoe and the surface such as oil or a banana peel, you would probably fall. This is because of the reduced friction.
This concept does not only exist on a board. Think about how many times you have used your earphones or headphones to listen to music or watch a program. How do you imagine you were able to listen? Well, your earphones have a magnet inside them. When you plug them to an electricity source, the magnet is able to create an electromagnetic field that results in the sound waves enabling you to listen to your music.
Everyone experiences inertia almost every day in their life. Whenever we use cars or other modes of transport, we are always encouraged to buckle up. Wearing a seat belt is encouraged because it guards you in the event of an accident and minimizes the injuries that could result from a collision. The seat belt is meant to prevent you from moving forward in a collision. This resistance is known as inertia.
When we prepare food, we probably never wonder how heat is transferred and enables us to have cooked food. The Physics behind this phenomenon is that heat is a form of transferable energy and can be transferred from one medium to another. For instance, you can put a pot of cold water on the stove and immediately, heat starts transferring to the pot making it hotter. The phenomenon is known as conduction. The water molecules at the bottom get heated fast and move to the top surface as they become lighter and the ones at the top move to the bottom surface.
We must have applied pressure countless times without knowing it. For example, when you cut a fruit, you will realize that when holding the knife, you have to firmly hold it and apply pressure in order to cut easily. The more the force applied, the easier it becomes to cut the fruit. The same principle applies for the knives as those with a smaller surface area cut easily compared to those with a blunt edge. You will realize that the blunt knife is more difficult to cut an object compared to the sharper knife.
