acceleration
Let an agent explain acceleration and compute it in problems, distinguish related concepts such as proper and tidal acceleration, describe measurement, and separate metaphorical senses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain acceleration and compute it in problems, distinguish related concepts such as proper and tidal acceleration, describe measurement, and separate metaphorical senses.
The rate of change of velocity with time, a vector quantity measured in metres per second squared, including the acceleration of free fall, uniform and variable acceleration, deceleration, proper acceleration felt by an accelerometer and tidal acceleration in orbital mechanics; acceleration links force and mass through Newton second law and appears in vehicles, sports, engineering and everyday experience, and metaphorically in social acceleration.
What it is for: Change of velocity over time.
It can be explain and compute acceleration; distinguish kinds of acceleration; describe measurement; separate metaphorical senses.
Distinguishing features
