Introduction The question of how aeroplanes stay up in the air has a very interesting answer. The physics behind it isn’t so complicated and can be easily understood if you understand what aerofoils are. To understand aerofoils, one must first understand what forces aid in keeping aeroplanes up. There are four such forces known as […]
Introduction The accelerometer is a device used to measure the acceleration of an object. The sensors present in an accelerometer allow us to measure and analyse both linear as well as angular acceleration. This device has a wide range of applications in our day to day life and forms a vital component of numerous basic […]
Introduction Everything in the universe consists of tiny particles called molecules, which are classified based on the distance and the attractive force between their constituents. Different substances have distinct properties such as mass, temperature, density, volume, pressure, etc. The process of transfer of heat is achieved through three different processes in matter, namely, conduction, convection, […]
Introduction In thermodynamics, we explore various variables, including temperature, pressure, volume, entropy, heat, etc. These variables form the foundation for thermodynamic processes, which may be classified into isothermal, isobaric, adiabatic processes, etc. In an adiabatic process, thermodynamic variables can change value so long as no exchange of heat occurs. There are two critical requirements for […]
Introduction Acoustics is a branch of physics that deals with the study of sound, including its generation, transmission, and effects. It encompasses a variety of topics, including mechanical waves in different mediums and the study of various sounds such as vibrations, noises, ultrasounds, and infrasounds. There are various sub-disciplines of acoustics, including aeroacoustics, bioacoustics, and […]
Introduction Acceleration represents the change in velocity of an object. It can either be positive or negative, depending on whether the final velocity is greater or less than the initial velocity. Thus, if the velocity of an object is decreasing with time, it is said to possess negative acceleration or retardation. Acceleration is a vector […]
Introduction Various optical systems, including lenses, mirrors, and spherical mirrors, reflect or diverge light to create various kinds of images. Rules of reflection and laws of refraction are the two fundamental laws that govern picture generation. In the creation of images, these laws are crucial. Different-sized pictures are created at various positions when light is […]
Introduction Let’s start with a fascinating experiment that you may have witnessed in your daily life. Insert a pencil or pen into a beaker of water. When you look at the pencil from outside the beaker, what do you notice? It will show up where it shouldn’t be, as you’ll discover. As a result of […]
Introduction An accelerometer is a tool used to measure the acceleration of a body. We are able to monitor and analyse both linear and angular acceleration using the accelerometer’s sensor. This function is used by us in many aspects of daily life and is a requirement for many fundamental systems and gadgets. An accelerometer, which […]
