- In kinematics, absement (or absition) is a measure of sustained displacement of an object from its initial position, i.e. a measure of how far away and for how long. The word absement is a portmanteau of the words absence and displacement. Similarly, absition is a portmanteau of the words absence and position. Absement changes as an object remains displaced and stays constant as the object resides at the initial position. It is the first time-integral of the displacement (i.e. absement is the area under a displacement vs. time graph), so the displacement is the rate of change (first time-derivative) of the absement. The dimension of absement is length multiplied by time. Its SI unit is meter second (m·s), which corresponds to an object having been displaced by 1 meter for 1 second. This is not to be confused with a meter per second (m/s), a unit of velocity, the time-derivative of position. For example, opening the gate of a gate valve (of rectangular cross section) by 1 mm for 10 seconds yields the same absement of 10 mm·s as opening it by 5 mm for 2 seconds. The amount of water having flowed through it is linearly proportional to the absement of the gate, so it is also the same in both cases. (en)
- Zinematikan absemendua edo absizioa objektu batek bere hasierako posiziotik izandako desplazamendua, denboran zehar iraunkorra, adierazten duen neurria da; adibidez, zeinen urrun dagoen jatorrizko posiziotik eta zenbat denboran zehar. Absemenduaren balioa behatutako objektua bere jatorrizko posiziotik desplazatua dagoen bitartean aldatuz doa. Hori dela eta, desplazamenduaren lehen integrala bezala adieraz daiteke matematikoki (edota desplazamendu eta denbora grafiko batean beheko azalera); ondorioz, desplazamendua absemenduaren deribatua da. Absemenduaren dimentsioa luzera denboraz biderkatua da. Horrenbestez, bere unitatea Nazioarteko Unitate Sisteman metro segundoa (m·s) da, hau da segundo batean guztira jatorritik metro batez desplazatuta egon den objektuarekin bat datorrena; ez bedi unitate hau nahasi abiaduraren metro segundoko (m/s) unitateekin. Absemendu hitza absentzia eta desplazamendu hitzen elkarketa da. (eu)
