Centre of mass formula class 11
WebSuppose you take 2 similar tennis balls and put them a bit apart, you see that the centre of mass of the two balls would be their centre. If one of these balls was heavier, the centre of mass will shift towards the heavier ball. But if you take a cricket bat, the centre of mass would be below the centre of the bat, in the lower half. WebPhysics Notes Class 11 CHAPTER 7 SYSTEM OF PARTICLES AND ROTATIONAL MOTION Centre of Mass Centre of mass of a system is the point that behaves as whole mass of the system is concentrated at it and all external forces are acting on it. ... Its unit is ‘joule-second’ and its dimensional formula is [ML2T-1]. Torque, τ = dL/dt

The mass element considered is a thin ring between x and x+dx with thickness dx and … WebThe center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For …
WebIt is defined as the distance from the axis of rotation to a point where whole mass of the rotating body supposed to be concentrated. It is denoted by ‘K’. If ‘K’ is radius of gyration. Then I = mK 2. Important Points: The moment of inertia of a body depends on the mass of the body and its distribution about the axis of rotation. WebThe formula of the centre of mass for the two-particle system is r cm = (m 1 r 1 +m 2 r 2 )/(m 1 +m 2 ) Where m 1 and m 2 are masses of two objects and r 1 and r 2 are their …
