Is displacement represented by Δd or Δs?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Displacement is commonly represented by Δs (delta s) in many physics textbooks, though Δd (delta d) is also used in some contexts. The Greek letter delta (Δ) means "change in," so both notations indicate a change in position. The symbol s is traditional for displacement in equations of motion, while d might be used when emphasizing the directional aspect or in vector notation.
