Every wave carries energy. The energy of some waves, such as earthquake energy, maybe directly seen. Similarly, wave energy manifests itself in the churning of… Read More
Vector operations are used almost everywhere in the field of physics. Many times these operations include addition, subtraction, and multiplication. Addition and subtraction can be… Read More
Almost all the work in today’s era is done online. Internet usage has drastically increased. Here, everything is in the form of  “data” and as… Read More
Thermodynamics has become an integral element of our daily lives. Whether you’re in a car, sitting comfortably in an air-conditioned room, or sipping a cold… Read More
Two vectors or a vector and a scalar can be multiplied. There are mainly two kinds of products of vectors in physics, scalar multiplication of… Read More
A wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities in physics, mathematics, and related subjects, commonly described by a… Read More
Privacy etymologically means “state of being alone and not watched by others”. The word privacy is derived from the Latin word “privatus” which means restricted,… Read More
Have ever wondered how does a heat engine work? or what’s going in a glass of water kept on the table? When we normally observe… Read More
Hydraulic machines are used in a lot of mechanical devices, from our cars to the springs used in trains. Hydraulic systems are involved. These systems… Read More
Frictional forces are in almost every aspect of the physical world. These forces oppose the motion of the object against each other. In this way,… Read More
Pascal’s law relates pressure and the height of the static fluids. A static fluid is defined as a fluid that is not in motion. When… Read More
When an object gains kinetic energy and changes position, it is known to be in motion. There are three types of motion possible, one dimensional,… Read More
Friction is a force that resists the motion between two surfaces. While it is mostly responsible for resistance against motion, it is also responsible for… Read More
One of the four laws of thermodynamics is the zeroth law of thermodynamics. The zeroth law of thermodynamics, interestingly enough, was formulated considerably later than… Read More
A body is said to be in equilibrium if the forces and moments applied on the body cancel each other out and there is no… Read More
