Answer
Logical operators represent conceptual operations (join, project, filter).
Physical operators are real engine implementations (hash join, nested loop, merge join).
Quick Answer
Logical operators are the high-level operations in the plan: Filter, Join, Aggregate, Sort. Physical operators are the specific algorithms chosen: Nested Loops (for join), Hash Match (for join or aggregate), Sort (for ordering). One logical operation maps to one physical operator — understanding both helps you read execution plans.
