Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero.
Center of mass = [(mass of a point object)*(distance of that point from origin)]/(Total mass)
For a rigid body we need to integrate this expression.

How do you calculate volume when mass and density are given?
Density = Mass/Volume so Volume = Mass/Density. Provided the object is solid.
What is the formula for mass of solid?
nM=m moles of solid multiplied by Molar mass (Atomic mass on periodic table) = Mass of solid
Where is center of mass of a sphere?
The center of mass of a sphere is its geometric center.
What is the density of 3cm by 3 cm by 3cm?
The volume of a rectangular solid with those dimensions is 27 cm3.If we also knew its mass, then we could calculate its density.
What is the center of mass of an equilateral triangle?
Center of mass of an equilateral triangle is located at its geometric center (centroid).
How do you find the center of mass of the raindrop?
To find the center of mass of a raindrop, you can calculate it by considering the raindrop as a uniform solid object. For a symmetric raindrop shape, the center of mass will lie at the geometric center. For irregular shapes, you can divide the raindrop into smaller parts, calculate the center of mass for each part, and then find the overall center of mass using these individual centers.
Is center of gravity lies where there is no mass?
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
Where is the centre of mass?
The center of mass is the point where an object's mass is evenly distributed in all directions. It can be located within the object itself or outside of it depending on the object's shape and distribution of mass.
What is the center of mass of a solid cylinder?
The center of mass of a solid cylinder is at its geometric center, which is the midpoint of its axis. This point represents the balance point of the cylinder, where its mass is evenly distributed in all directions.
Does the center of mass of a solid subject necessirly lie within the objects if not give examples?
No, the center of mass of a solid object does not necessarily have to lie within the object. For example, a hollow sphere or a ring has its center of mass located outside of its physical structure. This is because the distribution of mass in these objects is not uniform.
How is the Hfusion used to calculate the needed to melt the mass of a solid?
Grams solid mol/g Hfusion
How is stoichiometery used to calculate energy absorbed when a mass of a solid melts?
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.
Two unequal masses are attached to the ends of a solid rod. which mass is nearest to the Centre of Mass lighter or heavier?
The heavier mass will be nearest to the center of mass. The concept behind this is related to the one that explains the center of gravity. The center of mass and the center of gravity are the same.
How can you find center of mass of solid hemisphere?
To find the center of mass of a solid hemisphere, you can divide it into elementary components, such as disks or cylindrical shells, and integrate their individual masses over the hemisphere's volume. By dividing the mass-weighted points by the total mass, you can determine the coordinates of the center of mass in three dimensions.
How do you calculate the center of mass in a fuzzy washing machine?
by alot of troble
How is stoichiometry used to calculate energy absorbed when mass of solid melts?
Grams solid × mol/g × Hfusion
How do you calculate volume when mass and density are given?
Density = Mass/Volume so Volume = Mass/Density. Provided the object is solid.
