What can we conclude about the motion of a body depicted by the following velocity-time graphs?
(N/A) $(i)$ The graph shows a horizontal line parallel to the time axis,indicating that the velocity remains constant over time. This represents a body moving with uniform velocity.
$(ii)$ The graph shows a straight line passing through the origin with a positive slope,indicating that the velocity increases linearly with time. This represents a body moving with uniform acceleration.
$(iii)$ The graph shows a straight line with a negative slope,indicating that the velocity decreases linearly with time until it reaches zero. This represents a body moving with uniform retardation (deceleration).
$(iv)$ The graph shows the velocity decreasing linearly to zero (uniform retardation),remaining at zero for a certain time interval (at rest),and then increasing linearly (uniform acceleration).
