PhysicalSystemData

For general access to the Wolfram Knowledgebase, use entities of type PhysicalSystem instead of PhysicalSystemData.

PhysicalSystemData[entity,property]

gives the value of the specified property for the physical system entity.

PhysicalSystemData[{entity1,entity2,…},property]

gives a list of property values for the specified physical system entities.

PhysicalSystemData[entity,property,annotation]

gives the specified annotation associated with the given property.
