Introduction Bar magnet is an equivalent to a Solenoid. We all have seen Bar magnets and played with them in our childhood. It has astounding properties of attracting certain kinds of materials. For example, it attracts iron but shows neutral behaviour towards plastic. Bar Magnets are made of some special ... Read More

Introduction Bell’s theorem is a very interesting concept of modern science and philosophy. The strange realm of quantum mechanics is often complicated, and at times, incalculable. More importantly, investigating quantum mechanics often leads us to the interface between the world of science and philosophy. You might not know this, but ... Read More

Introduction A barometer can be defined as a device that is used to measure atmospheric pressure. We all know that atmospheric pressure changes with altitudes below and above sea level. During the investigation made in Italy in the 17th century, it was known that the mercury barometer was used to ... Read More

Introduction Accuracy and Precision play an important role while measuring anything. It is not possible for measurements to be completely error-free. Thus, when we are performing scientific calculations, our answers will carry certain errors, which can vary each time we repeat the experiment. For example, the acceleration due to gravity ...

Introduction Angular displacement and its measurement are key concepts of Dynamics. The particle is considered to be in motion when it changes its position with respect to time. That means the particle is displaced from one position to another. The particle makes linear displacement if it is moving in linear ... Read More

Introduction Angular Momentum is a concept of rotational dynamics. We can classify motions of objects in two kinds of motions namely Translational and Rotational motions. In pure translatory motion every point of the body moves in a straight line. Each point covers the same distance in a given time interval. ... Read More

Introduction Radiation is an emission of energy in the form of waves or particles. This includes the emission of Alpha particle, Beta particle, and Gamma particle. Alpha particles are also denoted by Alpha rays or Alpha radiation. It has two protons and two neutrons. What is an Alpha Particle? ... Read More

Introduction Angle of incidence and its measurement is a key concept of Optics. Light rays when incident on the surface like walls and mirrors, will reflect and get dispersed in the environment. The science of optics studies the traversing of light and its changing characteristics when passing from one medium ... Read More

Introduction A wave is a continuous disturbance that propagates from one point to another point. There are different types of waves that travel through mediums. Mainly there are two types of waves. Mechanical waves: A wave that requires a medium to propagate. For example, sound signals travel in the medium, ... Read More

Introduction Balanced and Unbalanced forces decide the state of an object. In simple language, Force is the interaction between two objects. It is a push or pulls that changes its position and causes the change in velocity. It is capable of doing work to change the state (rest state or ... Read More
