Parts and their functions

• x–t curve (x = t²) (x–t वक्र (x = t²)) — A curved x–t graph means the velocity is changing.
• Chord PQ (जीवा PQ) — Its slope Δx/Δt is the average velocity between P and Q.
• Δx and Δt (Δx और Δt) — Shrink Δt → 0 and the chord turns into the tangent.
• Tangent at P (P पर स्पर्श-रेखा) — Slope of the tangent = instantaneous velocity v = dx/dt (here 8 m s⁻¹ at t = 4 s).
