Unity Physics System

An Intro to Rigidbody

Unity comes preloaded with artificial gravity and is automatically turn on as default. Once you apply the Rigidbody component to any object and hit play you can see the objects fall into oblivion. There are several options to experiment with in the rigidbody settings, including the mass, which is how heavy the object is, Drag which calculates how much resistance the objects has. By clicking Kinematic, the object stays stills.
