Rigidbody setup guide

According to the Untiy3D Technologies on : https://forum.unity.com/threads/is-rigidbody-mass-its-mass-or-weight.366263/
Mass != weight, it depend on the gravity, so we should make it simple, use it’s example :

A truck around 1000kg, Tennis ball 0.1kg, we can map Kg to Unity’s mass.

A adult should be 197.6 Pound, Convert to Kg = 89.6Kg

Ref : https://www.medicalnewstoday.com/articles/320917#average-weight-of-men-in-the-us
Ref : https://www.unitconverters.net/weight-and-mass/lbs-to-kg.htm

Adult human (upright position) = 1.0–1.3

Ref : https://en.wikipedia.org/wiki/Drag_coefficient

The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag.
