Fig. 2 (NCT). 6 shows ` x-t` plot of one dismensional motion a particle. Is it correct to say from the graph that the particle moves in a straight line for ` t lt 0 `and on a parabolic path form ` t gt 0 `? If not, suggest a suitable physical contxt for this graph.

Explanation

No, because the ` x-t` graph dies not represent the trajectory of the path followed by particle. From the graph . It is moted that at ` t=0`, x= 0.`
Context. The above garph can represent the motion of a body falling freely from a tower under gravity.
