Ernest Rutherford
Ernest Rutherford, a Zealand chemist is regarded as the “father of nuclear physics.” He was the first to propose that an atom comprises a small charged nucleus surrounded by empty space and are circled by tiny electrons which later, became known as the Rutherford model. He is credited with the discovery of protons and hypothesized…

J.J Thomson
J.J Thomson, an English physicist and a Nobel Laureate in Physics, is credited and honoured with the discovery of the electron, which was the first subatomic particles to be discovered. Thomson managed to show that cathode rays were composed of previously unknown negatively charged particles (electrons), which he calculated and inferred might have smaller bodies…

Albert Einstein
Albert Einstein Photon, also known as light quantum, is a tiny energy packet of electromagnetic radiation. This concept originated in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light. Albert Einstein was best known for his General and Special theory of relativity and the…

Derivation of Lens Formula
We know there are two types of lens: concave lens, and convex lens. These lenses are used as per the requirement and play an important role in the study of optics. Lens formula is a well-designed formula that is applicable for concave as well as convex lenses. The lens formula is used to find image…

Derivation Of Kinetic Energy
The kinetic energy of a body is the energy that it possessed due to its motion. Kinetic energy can be defined as the work needed to accelerate an object of a given mass from rest to its stated velocity. The derivation of kinetic energy is one of the most common questions asked in the examination.…

Derivation of Potential Energy
The derivation of potential energy is provided here. Potential energy is defined as the energy that is held by an object because of its position with respect to other objects. The SI unit of potential energy is joule whose symbol is J. Potential energy term was introduced by Scottish engineer and physicist William Rankine in the 19th…

Kinetic Gas Equation Derivation
What Is Kinetic Theory Of Gases? The kinetic theory of gases describes gas as a large number of submicroscopic particles such as atoms and molecules, all of which are in random and constant motion. The randomness arises from the particles collisions with each other and with the walls of the container. Derivation Of Kinetic Gas…

Derivation of Stoke`s Law
What is Stoke’s Law? Stoke’s Law is a mathematical equation that expresses the settling velocities of the small spherical particles in a fluid medium. The law is derived considering the forces acting on a particular particle as it sinks through the liquid column under the influence of gravity. The force that retards a sphere moving…

Unit of Mass
Before understanding the unit of mass it is very crucial for students to know what is mass. In simple terms, mass is the quantity of matter in an object. More significantly, it can be both a property of a physical body and a measure of its resistance to acceleration when some amount of force is…

Unit of Time
Time is an interesting concept and we all are very familiar with it and know about it. However, the measurement of time requires some specification of units. There are several different units of time and they are used accordingly mostly based on certain circumstances. What Is Time? Time is defined as the continued progess of…
