Which observation best indicates non-uniform acceleration?
A
Equal velocity changes in equal times
B
Unequal velocity changes in equal times
C
Zero displacement
D
A horizontal distance-time line

A correct analysis gives Unequal velocity changes in equal times when magnitude, direction, units and conditions are considered. The question tests whether the learner can distinguish the required quantity from related ideas and use the stated information without adding unsupported assumptions. The alternatives Equal velocity changes in equal times, Zero displacement, and A horizontal distance-time line do not satisfy the governing definition, graph interpretation, direction convention, or numerical relationship in this case. In examinations, identify the known quantities, keep SI units consistent, select a positive direction where needed, and apply the appropriate definition or equation. This also checks that the answer has a sensible magnitude and unit.
