KnowledgeBoat · Accepted Answer

(a) Below is the velocity-time graph for a body moving with uniform velocity: Example: In the fig. given below, a straight line AB, represents the velocity-time graph of a body moving with a uniform velocity 4 ms^-1 for 5 s. Displacement in 5 second = area of rectangle OABC = OC x OA = 5 x 4 = 20 m Hence, displacement = 20m The slope of the straight line AB is zero, therefore, its acceleration is zero. (b) Below is the velocity-time graph for a body moving with uniform acceleration: Example: The table below represents the velocity of a body at different instants, starting from rest. Time (s) | 0 | 1 | 2 | 3 | 4 | 5| 6| 7|8 ---------|---|---|---|---|---|--|--|--|-- Displacement (m) | 0 | 10 | 20 | 30 | 40 |50 |60|70|80 Distance travelled in 8 s = S = area of triangle OPQ = x base x height = x OQ x QP = x 8 x 80 = 320 m Acceleration of body = slope of line OP = = = 10 ms^-2 Hence, distance covered is 320 m and acceleration = 10 ms^-2
