Gravity
Gravity is theoretically a constant - no matter where you are relative to the object, as long as your distance is the same, you will be pulled towards that object.
Gravity in Space Engineers
In Space Engineers, gravity is a linear force that pulls engineers in a certain direction. Gravity is not absolute, and the direction can be changed simply by changing the direction of the gravity source. Additionally, since it is linear, it can be stacked. The force of multiple instances of gravity affecting a single object can be measured by xn m/s2, where x is the force of a single instance of gravity and n is the number of forces acting upon that object.
Gravity in Space Engineers is currently caused primarily by Gravity Generators. Gravity can only be measured in a single linear direction. Because of this, it is not radial, like in real life. For example, if you are under a ship with a gravity generator, in real life you would be pulled towards the ship, but in Space Engineers, you will continue traveling downward until you leave the range of influence of the Gravity Generator.
The current gravity being enacted upon you can be measured using the Gravity HUD.
