Free-fall time refers to the time it takes for an object to fall freely under the influence of gravity, without any air resistance or other forces acting on it. This concept is commonly studied in physics and is governed by the laws of motion. In a vacuum, where air resistance is negligible, an object will accelerate towards the Earth at a constant rate, typically \(9.81 \, \text{m/s}^2\) (the acceleration due to gravity).

An enneadecagon is a polygon with 19 sides and 19 angles. The name derives from the Greek words "ennea," meaning nine, and "deka," meaning ten, reflecting its 19 sides (9 + 10 = 19). Each internal angle of a regular enneadecagon is approximately 168.53 degrees.

An enneagonal antiprism is a type of polyhedron that consists of two parallel enneagonal (9-sided) polygons connected by a band of triangles. In more specific terms, it is characterized by the following features: 1. **Base Polygons**: The top and bottom faces are both enneagons, meaning each has nine sides. 2. **Lateral Faces**: There are a series of triangular lateral faces that connect the corresponding vertices of the two enneagons.
