What is the center of gravity of an object? The center of gravity of the object is:

The center of gravity is the point at which the resultant force of gravity is applied to the object, and the position of the center of gravity of the object is determined by the geometry of the object and the mass distribution of each part of the object. The center of gravity of an evenly distributed and regularly shaped object has its geometric midpoint. In general, the center of gravity of an object may be within or outside the shape of the object.

1) The shape of the object changes, and its center of gravity position may not change. For example, a cube with a uniform mass distribution has its center of gravity at the geometric center. When the cube becomes a cuboid, its center of gravity remains at its geometric center.

2) The position of the center of gravity of the object relative to the object is constant, and it does not change with the change of the position where the object is placed.

Center of gravity]: The point at which the resultant force of gravity is applied to each part of the object. In cases where the gravitational forces on the internal parts of the object can be regarded as parallel forces, the center of gravity is a fixed point, independent of where the object is located and how it is placed, and coincides with the position of the center of mass.

The common way to find the center of gravity of the general object is: hang the object with a line, when balancing, the point of action (center of gravity) of the resultant force must be on the suspension line (or its extension line), and then change the suspension point to another point on the object, and then make it balanced, then the center of gravity must also be on the new suspension line (or its extension line), and the focus of the front and rear lines is the position of the center of gravity. For example, if the ideal position of the roulette wheel of the permanent magnet gravity magic wheel remains unchanged, it is suspended on a certain round edge of the roulette wheel and a point on a certain side of the wheel with a difference of 90 degrees, and the focus of the two center lines is the center of gravity.

The center of gravity is the pole of a thing, and in Feng Shui, the "center of gravity" is the pole and the bottom plate.

The center of the garden is the center of gravity, the intersection of the two diagonal corners of the square is the center of gravity, and the irregular figure is hung naturally in two different places with a line, and the intersection of the two lines is the center of gravity!

The center of gravity is the point of action of the resultant force of gravity on the object.

It can be assumed that if the volume of an object is reduced to 0, then it is on the center of gravity.

The reason why cans are able to stand diagonally is because the center of gravity is lowered when there is less liquid.

The center of gravity of the object is (the point at which the gravitational force is applied to the slag grip part of the object).

The object makes the following sentence:

1.Reality is made up of two imperfect objects that produce happiness in the fusion and collision of imperfections that collide side by side.

2.Starting with bacteria and single cells and ending with humans, every organism has a perceptible boundary that marks where it begins and ends.

3.A person climbs the rod upwards at a constant speed, imagining that the contact surface light scatters the beam and slips, and the person has a tendency to slide downward relative to the rod, and the direction of the static friction force on the object is the same as the direction of movement of the person.

4.Phagocytic cells in humans and other animals are divided into full-time and non-full-time, and the difference between the two lies in the obvious degree of phagocytic effect.

The center of gravity of an object is the gravitational force that affects every tiny part of the object, and these gravitational forces can be approximated as the converging force system that intersects at the center of the earth. Since the size of an object is much smaller than the radius of the Earth, the gravitational force acting on an object in general can be approximated as a parallel force system, and the total weight of the object is the resultant force of these gravitational forces.

If the volume and shape of an object are constant, the gravitational force on the object will always pass through a determined point in the coordinate system fixed to the object, i.e., the center of gravity, regardless of the direction the object is in to the ground. The center of gravity is not necessarily on the object, for example the center of gravity of a ring is not on the ring, but on its center of symmetry. In the case of an object with uneven mass distribution, the position of the center of gravity is not only related to the shape of the object, but also to the distribution of mass within the object.

The center of gravity of a truck changes with how much is loaded and where it is loaded, and the center of gravity of a crane changes with the weight and height of the object being lifted.

Not necessarily. The center of gravity is the point at which the resultant force of all the constituent fulcrums passes through the object in any direction in the gravitational field. The center of gravity of a regular and uniform object is its geometric center.

The center of gravity of an irregular object can be determined by the suspension method. The center of gravity of an object, not necessarily on the object.

The center of gravity is the equivalent point of gravity of the whole, in fact, every part of the object is subject to gravity, and the force of other parts can be moved to the center of gravity, so that the problem is very simple, the center of gravity of a regular shape object hits its geometric center, but it is not a real gravity action point such as a uniform ring, its center of gravity is on the center of the circle, not on the ring.

Example: A ring, the center of gravity is not on the ring.

Here are some ways to find the center of gravity of an object with an irregular shape or uneven mass.

a.Suspension method

Apply only to thin sheets (not necessarily uniform). First find a thin rope, find a point on the object, hang it with a rope, draw the gravity line after the object is stationary, and find a little bit of suspension in the same way, the intersection of the two gravity lines is the center of gravity of the object.

b.Support method

Apply only to fine sticks (not necessarily uniform). Supporting the object with a fulcrum, constantly changing position, the more stable the position, the closer to the center of gravity.

One possible workaround is to use two fulcrums to support and then apply a smaller force to bring the two fulcrums closer together, because the fulcrum closer to the center of gravity will have more friction, so the object will move with it, bringing the other fulcrum closer to the center of gravity, so that the approximate position of the center of gravity can be found.

c.Pintop method

The same applies only to thin sheets. Use a thin needle against the underside of the board, and when the board is able to maintain balance, the top of the needle is positioned close to the center of gravity.

In the same way as the support method, you can use the method of approaching three thin needles to each other to find the range of the center of gravity, but this is not as convenient as the workaround of the support method.

d.Use the plumb line to find the center of gravity(Any shape, uniform texture).

Hang it with a rope at one end of it, and then hang it on this end with a plumb line (trace it down). Then use the same method to make another line. The intersection of two lines is its center of gravity.
