Look at the graphs (a) to (d) Figure carefully and state, with reasons, which of these cannot possibly represent one-dimensional motion of a particle.
Figure shows the x-t plot of one-dimensional motion of a particle. Is it correct to say from the graph that the particle moves in a straight line for t < 0 and on a parabolic path for t > 0? If not, suggest a suitable physical context for this graph.
In which of the following examples of motion, can the body be considered approximately a point object:
(a) a railway carriage moving without jerks between two stations.
(b) a monkey sitting on top of a man cycling smoothly on a circular track.
(c) a spinning cricket ball that turns sharply on hitting the ground.
(d) a tumbling beaker that has slipped off the edge of a table.
Read each statement below carefully and state with reasons and examples, if it is true or false;
A particle in one-dimensional motion with zero speed at an instant may have non-zero acceleration at that instant
