The velocity time graph of a particle is given by –

  • Calculate distance and displacement of particle from given v – t graph. 
  • Specify the time for which particle undergone acceleration, retardation and moves with constant velocity. 
  • Calculate acceleration, retardation from given v – t graph. 
  • Draw acceleration-time graph of given v – t graph.

(i) distance = area of ∆OAB + area of trapezium 

BCDE = 12 + 28 = 40 m 

(ii) displacement area of ∆OAB – area of trapezium 

BCDE = 12 – 28 = – 16 m

  • times acc.(0 ≤ t ≤ 4) and (12 ≤ t ≤ 16) 
  • retardation (4 ≤ t ≤ 8) 
  • constant velocity (8 ≤ t ≤ 12)
