the center mass of an object is in the center of such objects. you can find it by spining the object.
:)
In this case, the center of mass will be closer to the object with greater mass.
For a single body, the center of gravity (center of mass) must be within the object. It is the single point at which all of an object's mass can be considered to act. For multiple bodies in a system, the center of mass can fall within a body or anywhere between bodies. The joint center of mass is called the "barycenter."
How can you find the center of mass of an object like a bottle rocket?
The center of gravity always lies within an object, and is the location at which the entire mass can be considered acting at a single point.For a system of more than one object, the center of gravity can lie anywhere between the farthest points of the objects, depending on the distribution of mass. The center of mass is called the barycenter.
Mass doesn't change. Mass the is substance of an object, moving it around won't affect how much mass it has, only adding or subtracting from the object would affect the quantity of mass. The weight would change because gravity is inversely proportional to distance but not the mass.
Center of mass is the average position of the mass of an object.
no
If the object is homogeneous, its center of mass is in its geometrical center. And if it is small compared to Earth, its center of gravity is, for all practical purposes, its center of mass.
The simplest answer is to add the mass at the center of mass. In that case, the total mass will increase, but not the center of mass. If the additional mass is not added at the center of mass, then it must be balanced with more mass at a location on the object that depends upon the object's shape. That's where things get complicated.
center of mass
The only factor that affects the center of gravity is how the mass of an object is distributed.
mass
mass
It is a point where conceptually the entire mass of an object can be considered to be concentrated
The object's mass, and how far you are from its center of mass.
In this case, the center of mass will be closer to the object with greater mass.
This is called either the center of gravity or the center of mass.
