maxwell law of molecular velocities

Recoil of a Gun - When a bullet is fired from a gun, the gases produced in the barrel exerts a tremendous force on the bullet (action force). As a result, the bullet moves forward with a great velocity called the muzzle velocity. The bullet at the same time exerts an equal force..

Newton's Second Law of Motion - Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the veloc..

The second law of motion improves our understanding of most types of motion involving a force. We get to understand that if a body is pushed with a stronger force, it accelerates at a faster rate and vice versa. We understand that if two different bodies are pushed with an equal force, th..

Introduction - Gas is one of the three states of matter - the other two being liquid and solid. A gas differs from a solid and a liquid in a number of ways. A gas fills entire space available to it and therefore it has no definite shape or volume. The molecules in a gas are in a continuous motion i..

Graham's law is useful in: Separation of gases having different densities by diffusion. Determining the densities and molecular masses of unknown gases by comparing their rates of diffusion with known gases. Separating the isotopes of some of the element..

Hence, if angular momentum remains constant, areal velocity should also remain constant. Kepler's second law states that, area swept by the radius vector of the planet in equal intervals of time is same or in other words, areal velocity of the planet is constan..

From Newton's third law of motion we know that whenever a force is applied on a body there will be an equal and opposite reaction. Action and reaction forces result in change in velocities of both the bodies which in turn change the momenta of these bodies. In an elastic collisi..

Introduction - The word force in common usage refers to a push or pull. The word Mass is also just as familiar as the word force. A super tanker is one that contains an enormous amount of mass. In comparison a coin does not contain much mass. During the seventeenth century Newton developed three im..

Newton's Second Law of Motion - The rate of change of momentum of a body is proportional to the applied force and takes place in the direction in which the force is applied. For a constant mass system We have already learnt that the rate of change of velocity is called accelerat..

. The bottom block will sail out from under, and the rest of the stack will not be toppled but will drop down still in a pile. It is not immediately obvious that a body moving with uniform velocity in a straight line tends to go on moving forever without coming to rest. The fact is that n..
