Are center of mass and center of gravity the same?

centroid is a geometrical centre of a plane figure or an object, it divides the shape into regions of equal moments. whereas the centre of a gravity is the point through which the weight of a body acts. the term centre of gravity applies to the bodies with mass and weight while the term centroid applies to plane areas.

I don’t see any difference between the two forms except the spelling. Center is commonly regarded as an American spelling, whereas in Britain, people tend to spell it as centre. This is similar to some words like meter and metre, color and colour, etc. The spelling centre is standard in UK English.

The center of gravity (CG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human’s center of gravity can change as he takes on different positions, but in many other objects, it’s a fixed location.

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.

Centripetal force is defined as, “The component of force acting on a body in curvilinear motion that is directed toward the center of curvature or axis of rotation,” while centrifugal force is defined as, “The apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of

In physics, the center of mass is the arithmetic mean of all points weighted by the local density or specific weight. If a physical object has uniform density, then its center of mass is the same as the centroid of its shape.

To find the centroid of a triangle, use the formula from the preceding section that locates a point two-thirds of the distance from the vertex to the midpoint of the opposite side. For example, to find the centroid of a triangle with vertices at (0,0), (12,0) and (3,9), first find the midpoint of one of the sides.

A centroid of a triangle is the point where the three medians of the triangle meet. A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle. The centroid is also called the center of gravity of the triangle.

The Centroid of a Triangle Divides Each Median in the Ratio 1:2. A median is the line from a midpoint of a side to the opposite vertex.

The centroid, orthocenter, and circumcenter all fall in a straight line. The centroid is always between the orthocenter and the circumcenter. In obtuse triangles, the circumcenter is always outside the triangle opposite the largest angle.

The point where the three “altitudes” of a triangle meet. An “altitude” is a line that goes through a vertex (corner point) and is at right angles to the opposite side. Try moving the points below, and notice: the orthocenter can be inside or outside of the triangle.

First let’s look at an isosceles triangle: This triangle has 2 sides of equal length. You can see that in these types of triangles, all 4 centers lie on the Euler Line.

The circumcenter of an obtuse isosceles triangle is outside the triangle and the perpendicular bisector passes through the obtuse angle of the triangle. Let’s also note where the circumcenter gets its name. The circumcenter is also the center of circle that the triangle is circumscribed inside of.

It is located at the point where the triangle’s three altitudes intersect called a point of concurrency. The orthocenter is located inside an acute triangle, on a right triangle, and outside an obtuse triangle.

Intuitively this makes sense because the orthocenter is where the altitudes intersect. Hence, in a right triangle, the vertex of the right angle is where you would expect the altitudes to meet, at 90 degrees, where the legs of the right triangle are perpendicular.

The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side. There are therefore three altitudes in a triangle.

Definition of the Centroid. The centroid of a triangle is the point where the three medians of the triangle intersect. The medians are the segments that connect a vertex to the midpoint of the opposite side. In this image, point G is the centroid of triangle ABC.

Euler’s line (red) is a straight line through the centroid (orange), orthocenter (blue), circumcenter (green) and center of the nine-point circle (red).
