maxwell's law of velocity

Maxwell's Speed Distribution Law - The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell d..

The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation giving the distribution of mol..

Suppose a particle P is moving in a circle as shown below. Let O be the centre and OX be the X-axis. The position of the particle may be described by the angle q . Let the particle move to the position q + d q in a time dt. Assume that the particle keeps changing its position. Thus, we can def..

Variation of Mass with Velocity - According to Newton's second law of motion, F = ma If a constant force 'F' is applied to a body for a very long interval of time, the velocity of the body will go on increasing due to the acceleration produced in the body. This ve..

We have, Applying the law of parallelogram of vectors, Since, This equation gives the magnitude of the resultant velocity of the projectile at any time. The direction of the projectile is given by the angle equation, which the resultant velocity v makes with the horizo..

Expression for Velocity Vector - The curved line in the figure represents the trajectory of a particle. Let the particle be at P at time t. The position of p with reference to origin O is given by . Let the particle be at Q at time (t + D t). The position of Q with reference to P is given..

Consider an object of mass 'm' placed on the surface of the earth. According to Newton's law of gravitation, the gravitational pull of the earth on that object is given by Where F is the force of attraction between the earth and the object, M e is the mass of the earth and R e is the radi..

Stokes' Law - When small spherical bodies move through a viscous medium, the bodies drag the layers of the medium that are in contact with them. This dragging results in relative motion between different layers, which are away from the body. Therefore, a viscous drag comes into play, oppo..

Velocity of Sound in Gases (Newton's Formula) - We know that the properties of a medium that govern the propagation of a mechanical wave are: a restoring force an inertial mass The restoring force acting on the particles of the medium is intimately connected to the approximate elastic mod..

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..
