Question

Which of the following statements is not correct regarding the motion of a particle in a straight line?

• A. x-t graph is a parabola, if motion is uniformly accelerated
• B. v-t is a straight line inclined to the time axis, if motion is uniformly accelerated
• C. x-t graph is a straight line inclined to the time axis if motion is uniform and acceleration is zero
• D. v-t graph is a parabola if motion is uniform and acceleration is zero

Answer 1

Answer: (D)

v-t graph is a parabola if motion is uniform and acceleration is zero

Answer 2

For uniform motions with zero accelerations , v – t graph is a straight line parallel to the time axis.
