A sphere is a round-shaped object in three-dimensional space. All points on a sphere's surface are the same distance from its center point. Some examples of a sphere are a globe, marble, soccer ball and basketball. More »

A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though... More »

The moment of inertia of a sphere is I = 2/5 MR^2 for a solid sphere and I = 2/3 MR^2 for a thin spherical shell. This moment of inertia can be derived from the moment of inertia of a thin disk by summing the moments of ... More »

An oblique shape is an object that is distorted so that the top is not directly over the bottom. As a result, the object appears to lean at an angle. More »

Technically, a pendulum can be created with an object of any weight or shape attached to the end of a rod or string. However, a spherical object is preferred because it can be most easily assumed that the center of mass ... More »

Find the volume of a sphere by solving for the equation V=4/3*pi*r^3, where V is volume, r stands for radius and pi is 3.1459. Cube the radius, and multiply that number by pi and 4/3 for the volume. Pi delineates the rel... More »
