The center of mass is the mean position of the mass in an object. Then there’s the center of gravity, which is the point where gravity appears to act. For many objects, these two points are in exactly the same place. But they’re only the same when the gravitational field is uniform across an object.

What is the center of mass of an object?

The terms “center of mass” and “center of gravity” are used synonymously in a uniform gravity field to represent the unique point in an object or system which can be used to describe the system’s response to external forces and torques.

## What is the difference between centrifugal and centripetal force?

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

## How do you find the centroid?

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.
