Catalogs Discussion Forums -> Mechanics -> Plz....Can someone Explain me when to apply concept of Centre Of Mass ???????? URGENT !!!!!!!!!!!! -> Go to message
This Post 0 points    (0 Olaaa!! Perrrfect answer.   in 0 votes )   [?]

The center of mass of a system of particles is the point at which the system's whole mass can be considered to be concentrated for the purpose of calculations. The center of mass is a function only of the positions and masses of the particles that compose the system. In the case of a rigid body, the position of its center of mass is fixed in relation to the object (but not necessarily in contact with it). In the case of a loose distribution of masses in free space, such as, say, shot from a shotgun, the position of the center of mass is a point in space among them that may not correspond to the position of any individual mass.

 

The center of mass is often called the center of gravity, but this is only true in a system where the gravitational forces are uniform. For example, on the Earth, differences in the pull of gravity may safely be ignored.Barycenter may refer to the center of mass but is most commonly used when referring to the point at which the gravitational forces exerted by two objects are equal.

Catalogs Discussion Forums -> Non IIT Institutes -> How is VITEEE paper..i mean of wat level ques do they ask...??? -> Go to message
This Post 0 points    (0 Olaaa!! Perrrfect answer.   in 0 votes )   [?]

 Well , Steppin stone patience is what you require...It takes time to answer posts here..With a whole lot of spamming going on here. Coming back to question, VITEEE is kinda average paper. Not too tough nor easy. "A-V-E-R-A-G-E"...you just need speed..I think speed it the main factor...You just need to speed up for it..like i said from my experience it has an average collection of questions..Its just the speed where you lack. Have a look here : VIT-question or speed

For any other queries regarding just nudge Geetashree (she's in vit..,she can help you regarding it)...
