The Role of Physics in our Daily Life Essay

Comments · 576 Views

i'm back to teach you physics but not from any textbook but from the very textbook of life yes i'm going to tell you certain examples which work on the principle of different different concepts that we learn in physics yes guys as i have said this earlier many times that physic

 let's go forward and speak about the 10 examples of physics in everyday life aren't you excited i am so this will be one of the most fun sessions to do here because it gives me an opportunity to make you look at things from a different angle from something which we usually don't look at as a layman so guys without wasting any further time here come to the very first example and that is an alarm clock now obviously there are different ways of looking at an alarm clock but just close your eyes and think about the morning every morning when that alarm clock goes off what happens at that point of time the alarm clock the annoying sound of it wakes you up, right guys.

so an alarm clock definitely is a mechanical machine but the working principle which is able to wake you up is lying in the wave nature of sound yes sound is a mechanical wave and an alarm clock at a mechanical level produces those sound waves of definitely a very very very high frequency relatively a shrill voice shrill sound which wakes you up this is something that you learn in 11 standards in a chapter called as waves that is where you get to know how sound waves as a mechanical wave propagate through a medium okay second example is how a hot cup of tea gets colder so this is something which commonly you get to know in chemistry but you study a lot about it in physics as well yes guys the law is nothing but the law of thermodynamics.

what does it say it says that if you have any hot object coming in contact physically with any cold object then there will be a transfer of energy from a hot object to the cold object in this process the temperature of the hot body will fall down the temperature of the cold body will rise up till the time they both achieve the same temperature which we call as the situation of thermal equilibrium so that is why that hot cup of tea if you are not consuming it if it is placed on the table it will get colder only colder enough that it achieves the same temperature as the room temperature okay guys cool next one I don't know whether you do that or not during this pandemic definitely most of us are not able to go out even for good jogging.
