The artificial mass block creates mass on the place where it's connected, which allows ships to be affected by the artificial gravity. The effective mass is 2000 kg on small ships and 50000 kg on large ships, which means that the block is pulled down with the equivalent force of an object of 2000/50000 kg. Hence, if the overall mass of the ship is greater than this, it will be pulled with a slower acceleration than the actual acceleration of the gravity affecting it. The artificial mass block is the first block to be affected by gravity, and was introduced in patch 1.025.010.

Physics of Artificial Mass

Artificial Mass in Space Engineers employs a particularly interesting concept in physics: The idea that inertial mass and gravitational mass are not necessarily the same thing. Inertial mass describes how difficult it is to move an object. Gravitational mass describes how much gravitational fields affect an object. In real life these quantities are exactly equal (Though the reason why that should be is unclear).

With the Artificial Mass block in Space Engineers, we see a case where gravitational and inertial mass are not equivalent. Far more force is exerted on an active Artificial Mass block by a gravitational acceleration than by an inertial acceleration (a push).

It is also worth noting that Artificial Mass blocks can be used in conjunction with Gravity Generators to break Newton's third law. In Newton's third law, every action must have an equal and opposite reaction. However, Gravity Generators do not experience a force after exerting a force on an object, thus breaking Newton's third law. This can be exploited to create powerful amounts of thrust by attaching both Gravity Generators and Artificial Mass blocks to a ship.

Usage

The artificial mass block can be used to add gravity to ships and other objects. While it can be used to create realistic vessels that obey the laws of gravity, it is also useful for creating vehicles that require an anchor or stabilizing force, such as trams/rail vehicles or cars and rovers (as of Patch 1.027, artificial mass can be used in conjunction with Wheel blocks to create stable and mobile cars and rovers).
