Ijubane nejubane yizinto ezihlukene. Ijubane liyisilinganiso sebanga ngesikhathi. Ijubane liyisilinganiso sebanga ngokuhamba kwesikhathi endaweni ethile. Ijubane liyi-scalar futhi lingaba eliqondile kuphela. Ijubane liyi-vector futhi lingaba lihle noma libe libi. Ngokwesibonelo, into ehamba ngesivinini esingamakhilomitha angu-50 ngehora isitshela kuphela ukuthi ihamba ngesivinini esingakanani kodwa hhayi ukuthi ihamba ngakuphi. Into enesivinini esingu-+50 km/h isitshela ngesivinini sayo nokuthi ihamba phambili. Ngakolunye uhlangothi, into enesivinini esingu -50 km/h isitshela isivinini sayo nokuthi ihamba emuva.
