The average position of the various mass elements of a body or system, weighted according to their distances from that center of mass; that point in an isolated system that moves with constant velocity, according to Newton's first law of motion.
The "balance point" of a group of objects, where the mass can be assumed to be for purposes of mechanical calculations; equivalent to the center of gravity.
The point at which the total mass of a body or system is assumed to be centered and upon which the sum of the external forces can act.
the location in a body at which all its mass can be concentrated without affecting its response to gravity.
that point where the mass of an object could be concentrated without changing the mass' reaction to the forces
the balance point between two massive objects that is proportionally closer to the more massive object. It is the point where (mass object 1) × (object 1 distance from center of mass) = (mass object 2) × (object 2 distance from center of mass).
geometric point in the reference frame of a physical body where that body's mass can be said to reside for physical purposes (as a "point mass")
That point of a body or system of bodies which moves as though the system’s total mass was located at that point.
The point within a body at which all the mass could be located without changing its dynamical behavior.
The "average" position in space of a collection of massive bodies, weighted by their masses. In an isolated system this point moves with constant velocity, according to Newtonian mechanics.
A point ∈M is called the center of mass of the points if it is a point of global minimum of the function () = ∑ | Such a point is unique if all distances | | are less than radius of convexity.
1. The point in a system of bodies or an extended body at which the mass of the system may be considered to be concentrated and at which external forces may be considered to be applied. 2. Point representing the mean position of the matter in a body.
the point at which the object's mass can be assumed, for many purposes, to be concentrated.
Two bodies revolve around a common center, called the balance point of the system.
The center of mass is the location at which the entire mass of an object (or set of objects) may be considered for purposes of calculations. It is the point of the average weighted position in space of an object (or a collection of objects).
A point of an object in which its whole mass may be assumed concentrated with respect to outer forces. Coherence Property of a bundle of waves whose relative phases are spatially or temporally equal or constant (example: laser), as opposed to incoherent waves.
the point on a body where forces are applied
Within a system of masses, the point that can be used to represent the entire mass of the system. Massive bodies in space, such as binary stars, orbit around a center of mass.
The point about which the sum of all the linear moments of mass of the particles in a body is zero.
A point that pretends to represent the entire mass of a system of masses or a single rigid mass. Massive bodies in space orbit around a center of mass.
The average position of a collection of fragments, weighted by their masses. For example, the center of mass cm of two fragments with masses 1 and 2 and positions 1 and 2, respectively, is given by cm
The balance point of a body or system of masses. The point about which a body or system of masses rotates in the absence of external forces.
Given the trajectory of an object or system, the center of mass is the point that has the same acceleration as the object or system as a whole would have if its mass were concentrated at that point. In terms of force, the center of mass is the point at which a given net force acting on a system will produce the same acceleration as if the systemâ€(tm)s mass were concentrated at that point.
In physics, the center of mass of a system of particles is a specific point at which, for many purposes, the system's mass behaves as if it were concentrated. The center of mass is a function only of the positions and masses of the particles that comprise 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).
