Q 3.16 Look at the graphs (a) to (d) carefully and state, with reasons, which of these cannot possibly represent one-dimensional motion of a particle.
(a) The given x-t graph cannot represent the one-dimensional motion of a particle as the particle cannot be at two positions at the same instant.
(b) The given v-t graph cannot represent the one-dimensional motion of a particle as the particle cannot be travelling at two velocities at the same instant.
(c) The given speed-time graph cannot represent the one-dimensional motion of a particle as the particle cannot have negative speed.
(d) The given path length-time graph cannot represent the one-dimensional motion of a particle as the total path length cannot decrease.
