kinetic energy
Let an agent explain kinetic energy and its forms, relay formulas, units and examples from physics references, describe applications such as wind energy and particle physics, and distinguish kinetic from potential and thermal energy.
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 kinetic energy and its forms, relay formulas, units and examples from physics references, describe applications such as wind energy and particle physics, and distinguish kinetic from potential and thermal energy.
The energy an object possesses because of its motion, equal in classical mechanics to half the mass times the square of the speed for translation, with rotational kinetic energy for spinning bodies, relativistic corrections at high speed, and the kinetic energy operator in quantum mechanics; kinetic energy is transferred in collisions, converted with potential energy, harvested from wind and water, and measured for particles such as neutrons and ionising charged particles in physics and radiation science.
What it is for: Not applicable; a physical quantity.
It can be explain the concept and forms; relay formulas and units; describe applications; distinguish from other energy forms.
Distinguishing features
Motion dependence
Scalar quantity
Frame dependence
Conservation with potential energy
What it looks like

Physical character
classical formula: E = (1/2) m v^2 formula
SI unit: joule unit
rotational formula: E = (1/2) I omega^2 formula
How it is recognised
Energy of motion
Translational, rotational, relativistic and quantum forms; wind and particle kinetic energy
Potential energy depends on position; thermal energy is microscopic kinetic energy of molecules
