The weight of an object is determined by the force of gravity acting on it. The weight is the product of an object's mass and the acceleration due to gravity at that location.
The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform motion.
The point of application of a force is the location where the force is acting on an object. It is important because it determines how the object will respond to the force, such as the direction and magnitude of the resulting motion or deformation.
The mass of an object determines its inertia. Inertia is the resistance of an object to changes in its motion, and objects with greater mass have greater inertia.
Net force determines the motion of the object. If the net force acting on an object is not zero, the object will accelerate in the direction of the net force.
To a certain extent, it is arbitrary. The designer chooses based on: -practicality of measuring from datums or origins -critical faces, surfaces, or dimensions -application. Sometimes, datums for a part are kept the same as the ones chosen for the overall assembly, especially if the design is a collaborative effort.

The similarity between communicating about an object or product through a dimensioned drawing and a written description is that they are both used to describe it, and they can both be descriptive. The main difference is that a drawing is able to show a picture of it.

An extension line in engineering drawing is a thin, solid line that extends from the object being dimensioned to indicate the precise location of a dimension or measurement. These lines help clarify the boundaries and features of the object by visually connecting the dimension to the relevant part of the drawing. Typically, extension lines do not touch the object and are used in conjunction with dimension lines to ensure clear communication of measurements. They are essential for accurately conveying the size and geometry of components in technical drawings.

In a concave mirror, the location of an object relative to the focal point determines the characteristics and location of the image formed. When the object is beyond the center of curvature, the image is real, inverted, and smaller; when the object is at the center, the image is real, inverted, and the same size. If the object is between the focal point and the mirror, the image becomes virtual, upright, and larger. Thus, the position of the object directly influences whether the image is real or virtual, its orientation, and its size.
The mass of an object determines its inertia. Inertia is the resistance of an object to changes in its motion, and objects with greater mass have greater inertia.
Absolute location refers to the exact coordinates (latitude and longitude) of a place on the Earth's surface. Relative location, on the other hand, describes a place in relation to other landmarks or geographic features. Absolute location is fixed and precise, while relative location is more subjective and context-dependent.
