## Gas equation

From these two laws, we understand that the pressure, volume and absolute termperature of a gas are interrelated, and a change in any one produces a chage in the other two. Consider a given mass of a gas. Let its … Read more

When a sharp knock is given to a door, the moving finger has momentum. Once the door is struck, the momentum of the finger is reduced to zero in a very short interval of time, As a result the force … Read more

Mass Mass is the amount of matter contained in a body. Mass of a body is the measure of inertia. Mass is a scalar quantity. Its unit is kg in SI system and gram in C.G.S. system. Mass of a … Read more

There are three important equations of motion, that is: v = u + at s = ut + 1/2at2 V2 = u2 + 2as Here ‘u’ is the initial velocity, ‘v’ is the final velocity, ‘a’ is the uniform acceleration … Read more

A particle moving with variable velocity is said to possess acceleration. When a particle executes non-uniform motion, its velocity changes. Acceleration is defined as the rate of change of velocity. It is a vector quantity. The unit of acceleration is … Read more
