lavoisier conservation of mass

Stated by French chemist A. Lavoisier "During any physical or chemical change, the total mass of the products remains equal to the total mass of the reactants". Law of conservation is also known as 'Law of indestructibility of matter..

According to this law, during any physical or chemical change, the total mass of the products remains equal to the total mass of the reactants. Law of conservation of mass is also known as 'Law of indestructibility of matte..

Momentum Conservation and Motion of Centre of Mass - As we know, the linear momentum of a particle is defined as , where m is the mass and is the velocity, the momentum of an N particle system is the vector sum of the momenta of the N particles. If the external forces ..

If the external forces acting on the system add up to zero, the centre of mass moves with constant velocit..

Let us consider two situations Suppose a block of mass 'm' rests on a rough horizontal table. It is dragged horizontally towards right through a distance 'l', and back to its initial position. Let ' m ' be the coefficient of friction between the block and the table. Let us calculate the w..

Let us consider a body of mass 'm' being raised vertically to a height 'h' as in the figure (1). The work done is mgh. Suppose we take the body along the path as in figure (3). The work done during the horizontal motion is zero. Adding up the work done in the two vertical parts of the pat..

Conversion of gravitational potential energy to kinetic energy: When a body falls from a certain height, its kinetic energy increases. ..

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 on the gun in the o..
