Revision introduction
Describe a measurement with its value, SI unit and uncertainty. For constant acceleration, v=u+at and s=ut+½at². These equations require constant acceleration; do not apply them blindly to variable acceleration. Dimensional consistency is a necessary check but cannot determine a dimensionless numerical factor.
