Collisions Collision is an event that demands involvement and interaction of at least two objects. In course of occurrence of such event interaction amongst object occur and each object experiences impulsive forces – a force which occur for a very small duration, from other. This impulsive force is responsible for change in momentum of the object Read more about Collisions[…]
Electric Current Electric current is one of the most basic units within electrical and electronic science. Electric current is central to almost every element within electrical and electronic circuits, systems and design. Whether it is an electrical heater, a large electrical grid system, a mobile phone, computer, remote sensor node or whatever, the concept of Read more about Electric Current[…]
Centripetal Force When an object travels in a circle, even at constant speed, it is undergoing acceleration. In this case the acceleration acts not to increase or decrease the magnitude of the velocity vector, but rather to change its direction. Newton’s second Law tells us that in the absence of any outside Force, an object Read more about Centripetal Force[…]
Centrifugal Force The concept of centrifugal force rarely comes with an instruction manual like the Coriolis force and the inertial force, centrifugal force belongs to the category of fictitious forces, also called apparent forces or pseudo-forces. What is Centrifugal Force? A force is any cause capable of changing the speed or trajectory of a mass. Read more about Centrifugal Force[…]
Vector Product of Two Vectors The physical quantities may be broadly classified into the vectors and the scalars. The quantities with magnitude and direction both are known as vector quantities. What is a vector product? The vector product or the cross product of two vectors is a binary operation on two vectors in three dimensional Read more about Vector Product of Two Vectors[…]
Scalar Product of Two Vectors The physical quantities may be broadly classified into the vectors and the scalars. The quantities with magnitude and direction both are known as vector quantities while, the quantities with only magnitude are called scalar quantities. What is a Scalar Product? Scalar product is a special technique of multiplying two vectors. As Read more about Scalar Product of Two Vectors[…]
Kepler’s Third Law of Planetary Motion Kepler’s Third Law: Law of Harmonics or Law of periods The square of the orbital period of a planet is proportional to the cube of mean distance from the sun. We also say that, the semi – major axis of the ellipse, half the sum of smallest and greatest Read more about Kepler’s Third Law of Planetary Motion[…]
Kepler’s Second Law of Planetary Motion Kepler’s second law states that the orbiting satellite will speed up when it gets closer to the object at the focus. This is caused by the increased effect of gravity on the orbiting object as it gets nearer to what pulling it into the orbital path. The mathematical statement Read more about Kepler’s Second Law of Planetary Motion[…]
Kepler’s First Law of Planetary Motion Kepler’s laws of planetary motion, in astronomy and classical physics, laws describing the motions of the planets in the solar system. They were derived by the German astronomer Johannes Kepler, whose analysis of the observation of the 16th century Danish astronomer Tycho Brahe enabled him to announce his first Read more about Kepler’s First Law of Planetary Motion[…]
Isentropic Process Isentropic means constant entropy. A process during which the entropy remains constant is called an isentropic process, which is characterized by ΔS = 0 Or S₁ = S₂ for a process 1 – 2. If a process is both reversible and adiabatic, then it is an isentropic process. An isentropic process is an Read more about Isentropic Process[…]
