Question

An object is in unifrom motion along a straight line . What will be position-time graph for themotion of the object if
(a) ` x_(0_=+ve, v=+ ve (b) x_(0) =+ ve, v =- ve (c ) `x_(0) =- ve, v= + ve and (d) both `x_(0)` and `v` are negative ? The letters ` x_(0)` and `v` position of theobject at time `t=0` and v` represent posituion of the object at time `t=0` and uniform velocity of theobject respectively.

Answer 1

The position of the object at any time (t) while moving with uniform velocity along a straight line is given by, ` x= x_(0) + v t`
(a) If ` x_90) = + ve and v + ve, position-time grpgh will be as shown in Fig. 2 (a). 34 (a)
(b) If ` x_(0) = + ve amd `v =- ve`, the position-time graph will as shown in Fig. (a) 2.34 (b). (c ) If `x_(0) =- ve and v=+ ve`, the positio -time graph will be as shown in Fkig. 2 (a) . 34 (c ).
(d) If both ` x_(0) and u` are, negative the position-time graph will be as shown in Fig. 2 (a). 34 (d)`
