The linear velocity vector of this
BasePart|part’s assembly. It’s the rate of change in position of the assembly’s
BasePart/AssemblyCenterOfMass|center of mass in studs per second.
If you want to know the velocity at a point other than the assembly’s center of mass, use
Setting the velocity directly may lead to unrealistic motion. Using a
VectorForce constraint is preferred, or use
BasePart/ApplyImpulse if you want instantaneous change in velocity.
