| style="height:20px; width:200px; text-align:center;" |'''Electricity''' [[Energy Transfer|transfers energy]] into the [[Kinetic Energy Store]] of the motor when it accelerates. It also [[Energy Transfer|transfers energy]] into the [[Thermal Energy Store]] of the motor as the motor gets hotter. If the motor is used to lift an [[object]] then [[Energy Transfer|energy is transferred]] into the [[Gravitational Potential Energy Store]] of the object.

===Meaning===
'''Electricity''' is an [[Energy Transfer|energy transfer]] caused by the flow of [[electron]]s or [[ion]]s though a [[medium]].
===About Electricity===
: [[Electricity]] can perform [[Work Done#Work Done by Electricity|electrical work]] as the [[Electrostatic Field|electrostatic field]] inside a [[wire]] provides a [[force]] to move the [[electron]]s (or [[ion]]s).
[[Electricity]] has two [[property|properties]] that can be used to describe it:
*[[Electrical Current|Current]] - The rate of flow of [[Electrical Charge|charge]]; <math>I=\tfrac{Q}{t}</math>
*[[Potential Difference]] - The [[Work Done|work done]] per unit [[charge]]; <math>V=\tfrac{E}{q}</math>
