The Total solution for NCERT class 6-12
The figure shows the x-t plot of the one-dimensional motion of aparticle. Is it correct to say from the graph shows that the particle moves ina straight line for t < 0 and on a parabolic path for t >0? If not,suggest a suitable physical context for this graph.
It is not correct tosay that the particle moves in a straight line for t < 0 (i.e., -ve) and ona parabolic path for t > 0 (i.e., + ve) because the x-t graph does notrepresent the path of the particle.
A suitable physicalcontext for the graph can be the particle is dropped from the top of a tower att =0.
