Phase 1 (Acceleration: P to Q)
- The speed increases from 0 to V1 over time t1.
- This forms an upward-sloping line.
Phase 2 (Constant Speed: Q to R)
- The speed remains constant at V1 over time t2.
- This forms a horizontal line.
Phase 3 (Deceleration: R to S)
- The speed decreases from V1 to 0 over time t3.
- This forms a downward-sloping line.
The given speed-time graph consists of four distinct line segments, forming a closed shape with four sides. While it has a trapezoidal structure, the most general classification for it is a quadrilateral because a trapezoid is a specific type of quadrilateral.
