Question

define center of mass derive an expression for the center of mass of two particle system show that the center of mass of two particles of equal masses lies at the center of line joining them​

Answer 1

Answer:

The centre of mass (CoM) is the point relative to the system of particles in an object. This is that point of the system of particles that embarks the average position of the system in relation to the mass of the object. At the centre of mass, the weighted mass gives a sum equal to zero. It is the point where any uniform force applied on the object acts.

In other words, a particle’s centre of mass is the point where Newton’s law of motions applies perfectly. When force is applied to the centre of mass, the object as a system of particles moves in the direction of force without rotating. No matter what the shape of the object, the centre of mass helps understand the mechanism of force and motion of that object.

Answer 2

CENTER OF MASS (COM) :-

IT IS A POINT WHERE THE ENTIRE MASS OF A SYSTEM OF PARTICLES CAN BE SUPPOSED TO BE CONCENTRATED
