motion
Let an agent explain motion by kinematics, dynamics, frames of reference and everyday examples, and separate other senses of motion.
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 motion by kinematics, dynamics, frames of reference and everyday examples, and separate other senses of motion.
The change in position of an object with respect to a frame of reference over time, described in physics by displacement, velocity, acceleration and time, and explained by forces through the laws of motion.
What it is for: Describing and predicting how things move.
It can be describe motion with position, velocity and acceleration; apply Newton laws of motion; explain relative motion and frames; separate legal, meeting and other senses.
Distinguishing features
Relative to a frame of reference

How it is recognised
Displacement-time and velocity-time graphs
Linear, circular and oscillating motion
A motion in a meeting is a proposal
