force_gravity g_x g_y g_z

Gravitational acceleration.

In 1D, only the gravity in x-direction needs to be specified. In 2D, the gravity in x-direction and y-direction needs to be specified. In 3D, the gravity in x-direction, y-direction and z-direction needs to be specified.

See also force_gravity_time.
