India is the 2nd biggest aquaculture fish producer and the 3rd largest fish producing country globally. India contributes about 7 per cent to world fish production. India is also home to many fish biodiversity, and it is a 17-mega biodiversity-rich country. Around 40.3 million people were engaged in the primary capture fisheries sector—the country’s largest […]

Class 11, IIT JEE, Physics, Work-energy theorem, Work, Energy, and PowerHave you ever wondered why we can only cut with sharp objects or why we need special shoes to walk on snow or why you can’t hammer a nail without a sharp end into the wall, or why a single nail bursts the balloon, but a bed of balloons can’t do that? The concept of

Class 11, IIT JEE, Physics, Work-energy theorem, Work, Energy, and PowerA matrix is a form of representation of numbers or equations arranged in rows and columns like a rectangular table or box. The number of rows and columns specify the dimensions of the matrix. For example, if the matrix has 3 rows and 4 columns, it is said to be a 3*4 matrix. The product

Class 11, IIT JEE, Physics, Work-energy theorem, Work, Energy, and Power“Work” and “energy” are two terms we often hear and use in our daily lives. Work is a type of activity that involves a certain amount of physical as well as mental effort. To perform any work, you need energy. However, work and energy are not defined in such a way in physics. For example,

Class 11, IIT JEE, Physics, Work-energy theorem, Work, Energy, and PowerIntroduction The only way of defining energy is the capability to do work. There are mainly several forms of work, involving electrical work, mechanical work, and work in any gravitational or magnetic field. Work SI unit is the joule. The experts of physics and chemistry see work as a relation to energy. If there is
In a game of billiards, balls collide with each other at a certain speed. This action of two bodies coming in contact with each other due to an external force is called a collision. But what happens after a collision? Why does the momentum of one ball decrease while that of the other ball increases?

Class 11, IIT JEE, Laws of Motion, Newton’s laws of motion, PhysicsNewton’s second law of motion states the relationship between the mass of an object, its acceleration and the net force acting on it. But this law cannot be applied to some objects that gain or lose weight when they are in motion. Another equation needs to be derived for such objects with the help of

Class 11, IIT JEE, Laws of Motion, Newton’s laws of motion, PhysicsIntroduction Everyone well understands the rate at which the velocity of a body varies concerning time. It might be challenging to comprehend how an attribute characterised by a rate of change can be regarded as uniform in some instances. Because consistency in acceleration is so important, let us examine it thoroughly, mainly because it is

Class 11, IIT JEE, Laws of Motion, Newton’s laws of motion, PhysicsMeaning Things around us, such as the movements of a clock’s hands, the rotation of blades of a ceiling fan, the direction of a ball, the movement of an asteroid, and the earth’s rotation and revolution, are some examples of uniform motion. More precisely, uniform motion is the motion of an item in which the
A force is a push or pull that occurs as a result of one object’s interaction with another object. Forces come in a variety of shapes and sizes. Earlier in this lesson, a number of force types were classified into two categories based on whether the force was caused by touch or non-contact between the
