Line 11:
* [[Angle]] (angular position) and [[angular momentum]];
* [[Doppler effect|Doppler]] and range: the more we know about how far away a [[radar]] target is, the less we can know about the exact velocity of approach or retreat, and vice versa. In this case, the two dimensional function of doppler and range is known as a [[radar ambiguity function]] or '''radar ambiguity diagram'''.
* [[Electrical work]]: ℰde (''ℰ'' = [[electromotive force]]; ''e'' amount of charge)
* Magnetic work MdH (''M'' = magnetization; ''H'' = field)
* Surface energy: γdA (''γ'' = [[surface tension]] ; ''A'' = surface area)
* Elastic stretching: FdL (''F'' = elastic force; ''L'' length stretched)
* [[Gravitational potential energy]]: ψdm (''ψ'' = gravitational potential; ''m'' = mass)
