What can you conclude about the motion of a body depicted by the velocity-time graphs $(i)$,$(ii)$ and $(iii)$ given below?
(N/A) $(i)$ Uniform motion: The velocity of the body remains constant over time,meaning the acceleration is zero.
$(ii)$ Uniformly accelerated motion: The velocity of the body increases linearly with time,indicating a constant positive acceleration.
$(iii)$ Uniformly retarded motion (or deceleration): The velocity of the body decreases linearly with time,indicating a constant negative acceleration.
$(ii)$ Uniformly accelerated motion: The velocity of the body increases linearly with time,indicating a constant positive acceleration.
$(iii)$ Uniformly retarded motion (or deceleration): The velocity of the body decreases linearly with time,indicating a constant negative acceleration.
