How can the center of gravity of an irregular shape be determined?

For a general shaped object, there is a simple mechanical way to determine the center of gravity: If we just balance the object using a string or an edge, the point at which the object is balanced is the center of gravity. This procedure works well for irregularly shaped objects that are hard to balance.

Is the center of gravity always within the object?

The center of gravity may not lie inside the body itself if the body is concave but will always lie inside the body’s convex hull . If the body has uniform density, the center of gravity is also the body’s centroid .

What is the centre of substance with irregular shape is called?

centre of gravity The two do not always coincide, however. In some cases, such as hollow bodies or irregularly shaped objects, the centre of gravity (or centre of mass) may occur in space at a point external to the physical material—e.g., in the centre of a tennis ball or between the legs of a chair.

Can center of gravity lies outside the body?

Yes, the centre of gravity of a body can be outside it. The CG of a uniform ring is at its centre, a point which is not on the body.

How did you find the center of gravity of each shape?

You can find the center of gravity mathematically by taking the average or mean distribution of the weight of the object. You can also find the CG experimentally by either using a plumb line or finding the balance point.

Can the centre of gravity of an object be situated outside its material if yes give an example if no why?

So yes it can. We have examples in which the centre of gravity lies outside the material of the body. In case of a ring, it is situated at the centre of that circle. Hence the centre of gravity is situated outside the material of the body.

What are the factors that affect the center of gravity of an object?

The two factors that affect the force of gravity are mass and acceleration. Mass is how much matter is in an object. Objects with more mass are more…
