... “2mgh” as the force needed to lift a body a distance h, or the weight times the height. The author is not aware of how Leibniz handled the factor “2” on the left in eq. 4, or the factor “½” on the right in eq. 5. The same issue applies to Newton, as will be described later. Setting aside the factors ...

... matter is contained in an object. Two identical boxes, one empty and one full, have different masses. The box that's full has the greater mass, because it contains more stuff; more stuff, more mass. Mass is measured in kilograms, abbreviated kg.

Chapter 9 Rotational Motion
... Up to now, the main emphasis in the description of the motion of a body dealt with the translational motion of that body. But in addition to translating, a body can also rotate about some axis, called the axis of rotation. Therefore, for a complete description of the motion of a body we also need to ...

All objects can be represented roughly by polyhedra, and most 3D graphics software (such as DirectX and OpenGL) in essence can only render triangles. This has meant that the boundar ...
