* [[Latitude]]s south of the equator and [[longitude]]s west of the [[prime meridian]].
* [[Topography|Topographical]] features of the earth's surface are given a [[height]] above [[sea level]], which can be negative (e.g. the surface elevation of the [[Dead Sea]] or [[Death Valley]], or the elevation of the [[Thames Tideway Tunnel]]).
* [[Electrical circuits]]. When a battery is connected in reverse polarity, the voltage applied is said to be the opposite of its rated voltage. For example, a 6-volt battery connected in reverse applies a voltage of −6 volts.
* [[Ions]] have a positive or negative electrical charge.
* [[Wave impedance|Impedance]] of an AM broadcast tower used in multi-tower [[directional antenna]] arrays, which can be positive or negative.
