चित्र में $(a)$ से $(d)$ तक के ग्राफों को ध्यान से देखिए और देखकर बताइए कि इनमें से कौन-सा ग्राफ एकविमीय गति को संभवत: नहीं दर्शा सकता।
Solution
The given $x-t$ graph, shown in (a), does not represent one-dimensional motion of the particle. This is because a particle cannot have two positions at the same instant of time.
The given $v -t$ graph, shown in (b), does not represent one-dimensional motion of the particle. This is because a particle can never have two values of velocity at the same instant of time.
The given $v -t$ graph, shown in (c), does not represent one-dimensional motion of the particle. This is because speed being a scalar quantity cannot be negative.
The given $v -t$ graph, shown in (d), does not represent one-dimensional motion of the particle. This is because the total path length travelled by the particle cannot decrease with time.
