maada ni kitu chochote chenye uzito na kinachoweza kuchukua nafasi.maada imeudwa kwa chembechembe ndogo sana ziitwazo[atomi]. kwa kawaida maada inaweza kuwa katika hali kuu tatu ambazo ni yabisi,mango na gesi.maada huweza kubadilika pale tu joto linapo badilika.badiliko la maada linaweza kuwa kutoka gesi kwenda yabisi mfano mvuke kuwa barafu,yabisi kwenda gesi mfano barafu kuwa mvuke,kimiminika kuwa yabisi mfano maji kuwa barafu n.k

Tangu karne ya 20 ufafanuzi sahihi wa maada umeshindikana kutokana na maendeleo ya sayansi,nayo si jambo tena la msingi katika fizikia kama ilivyokuwa awali
| title = Mata
hivyo matawi mbalimbali ya sayansi yanatumia neno mata kwa maana tofauti tofauti

'''Mata''' (kutoka [[Kiingereza]] ''matter'': kwa [[Kiswahili]] pia "maada") ni neno pana linalojumlisha vyote vinavyoweza kuonekana, kusikika, kuguswa, kuchunguzwa n.k., ikiwemo hasa ''mata ya kawaida'' inayoundwa na [[atomi]] ambazo tena zinaundwa na [[kiini]] cha [[protoni]] na [[neutroni]], kikizungukwa na [[wingu]] la [[elektroni]].<ref name=Davies2>

Mata inapatikana kwa kawaida katika [[hali za mata|hali]] nne: [[mango]], [[kiowevu]], [[gesi]] na [[Utegili (fizikia)|plasma]].
Hivyo matawi mbalimbali ya [[sayansi]] yanatumia neno mata kwa maana tofautitofauti.<ref name=Davies>
