The center of gravity of an irregular lamina is the point at which the entire weight of the lamina can be considered to act. It can be determined by balancing the lamina on a point and finding the point of equilibrium. Mathematically, it can be calculated by finding the weighted average of the x and y coordinates of all the points on the lamina.

Does the position of the Metacentre depend on the position of the centre of gravity?
Yes, the position of the Metacentre depends on the position of the centre of gravity. If the centre of gravity is above the Metacentre, the ship will be stable. If the centre of gravity is below the Metacentre, the ship will be unstable.
Is the center of gravity always in the center of the object?
The earth pulls every molecule of an object in a downwards direction, or in other words every molecule of an object has a weight. We can add all the millions of tiny molecule weights together and get a single resultant force for the weight of the whole object. So an object behaves as if its whole weight was a single force which acts through a point G called its centre of gravity. An object of uniform thickness and density has its mass evenly spread throughout and its centre of gravity is at its geometrical centre. Some examples of objects with regular shapes and uniform densities are shown in the figures below. It is interesting to note the centre of gravity of an object is not necessarily inside the object.
Does gravity always act in the center of earth?
No, the gravity between Jupiter and its moons acts towards the centre of Jupiter.
Where does the centre of gravity of atmosphere of the earth lie?
It lies at the center of the Earth.
Does gravity push us toward the earth?
gravity pulls us towards the centre (core) of the earth. because bears.
What is the center of gravity for a lamina?
If the lamina is in two dimensions (i.e. not curled round into a third dimension) then the centre of gravity will be somewhere within the flat shape. The position of the centre of gravity will depend on the distribution of mass across the lamina. If the lamina is curled round into a third dimension then the centre of gravity will be somewhere within the volume enclosed, fully or partially, by the lamina; this may or may not be on the lamina.
Why is the center of gravity different between regular and irregular shapes?
Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?
How is the center of the gravity determined when an object is at rest or in motion?
If the object is a thin lamina with uniform thickness (e.g. a piece of paper), the the centre of gravity of the object is at its geometrical centre. It can be determined by suspending a load (e.g. pendulum) on an edge of the lamina twice and the point where the plumb lines intersect is the centre of gravity.
How the centre of gravity of irregular objects measure?
The center of gravity of irregular objects can be measured by hanging the object freely and observing where it balances perfectly. Another method is to calculate the average position of the weight distribution in each dimension. Computer software can also be used to model the object and determine its center of gravity.
How do you determine the centre of gravity of an irregular object?
The center of gravity of an irregular object can be determined by finding the point where the object would balance perfectly in any orientation. This can be done by supporting the object at different points and adjusting until it is balanced. The center of gravity is typically the point where all these balancing points intersect.
Where does the center of mass rectangular lamina lie?
The centre of mass of a rectangular lamina lies at the point of intersection of its diagonals.
Why must the intersection of the 3 lines be the center of GRAVITY of the irregularly shaped lamina?
Oh, dude, the intersection of the three lines must be the center of gravity of the irregularly shaped lamina because that's just how gravity works. Like, gravity pulls everything towards the center of mass, so if you want to find where all the forces balance out, you gotta look at where those lines meet. It's like the universe's way of saying, "Hey, this is where things chill out."
Does the position of the Metacentre depend on the position of the centre of gravity?
Yes, the position of the Metacentre depends on the position of the centre of gravity. If the centre of gravity is above the Metacentre, the ship will be stable. If the centre of gravity is below the Metacentre, the ship will be unstable.
Where does the center of gravity of a triangular lamina lie?
The center of gravity of a triangular lamina lies at the point of intersection of the medians of the triangle, which is also known as the centroid. It is located one-third of the distance from each vertex to the midpoint of the opposite side along the median.
Does the centroid of laminas always fall within the area of the lamina?
The centroid of a lamina does not always fall within its area. For simple shapes like rectangles or circles, the centroid is located within the shape. However, for more complex or irregular shapes, such as a crescent or a "U" shape, the centroid can fall outside the physical boundaries of the lamina. Thus, the position of the centroid depends on the specific geometry of the lamina.
Why is suns gravity only in the perimeter?
It isn't. Gravity can be viewed as emanating from the centre of a body with mass. As the distance increases from the centre then the gravity decreases.
Does the centre of gravity change on moon?
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
