Masaafada waa dhererka wadada uu maro shay. Masaafada waa tiro cabbir ah, tiro jireed oo leh cabbir iyo jiho keliya. Cutubka caalamiga ah ee masaafada waa mitirka, oo loo soo gaabiyo m. Astaanta masaafada waa s.

Barokaca waa isbeddelka booska shay. Barokaca waa tiro vector ah, tiro jireed oo leh baaxad iyo jiha labadaba. Jihada barokaca waxaa lagu tilmaami karaa jihada wadnaha (waqooyi, bari, koonfur, galbeed, iwm.) ama iyadoo la adeegsanayo ereyada bidix, midig, kor, ama hoos.
Baro su'aalaha tusaalaha ah ee soo socda si aad si fiican u fahamto fikradaha masaafada iyo barakicinta oo aad si sax ah oo sax ah u kala saari karto masaafada iyo barakicinta.
Tusaalaha dhibaatooyinka.
1. Arday ayaa lugeynaya 2 mitir bari. Waa maxay masaafada iyo barokaca ardaygu?
Dood
a = booska bilowga ah, b = booska kama dambaysta ah
Masaafada = 2 mitir
Tirada barokaca = 2 mitir, jihada barokaca = bari
2. Ardaygu wuxuu u lugeeyaa 2 mitir dhanka bari, ka dibna wuxuu u lugeeyaa 2 mitir dhanka galbeed. Waa maxay masaafada iyo barokaca ardaygu?
Dood
a = booska bilowga ah, b = booska kama dambaysta ah
Masaafada = 2 mitir + 2 mitir = 4 mitir
Baaxadda barokaca = 0.
Ardaydu ma dhaqaaqaan sababtoo ah booska ugu dambeeya wuxuu la mid yahay booska bilowga ah.
3. Ardaygu wuxuu u lugeeyaa 2 mitir dhanka bari, ka dibna wuxuu u lugeeyaa 1 mitir dhanka galbeed. Waa maxay masaafada iyo barokaca ardaygu?
Dood
a = booska bilowga ah, b = booska kama dambaysta ah
Masaafada = 2 mitir + 1 mitir = 3 mitir
Tirada barokaca = 2 mitir – 1 mitir = 1 mitir, jihada barokaca = bari.
