Look at the graphs (a) to (d) (Fig. 3.20) carefully and state, with reasons, which of these cannot possibly represent one-dimensional motion of a particle.
The given graphs are shown below:
The graph (a) does not represent one-dimensional motion. This is because at a particular time t , there are two positions of the object which is not possible in one-dimensional motion.
The graph (b) does not represent one-dimensional motion. This is because at a particular time t , the particle has two motions in opposite direction. It is an example of two-dimensional motion or motion in a plane.
The graph (c) is wrong because it shows negative speed of a particle. Speed of an object cannot be negative.
The graph (d) does not represent one-dimensional motion because the total path travelled by the particle cannot decrease with time but the graph shows the increase and decrease of the total path length with time.
