Molao oa Boraro oa Newton e bolela hore haeba ntho ea 1 e sebelisa matla nthong ea 2, ka nako e tšoanang ntho ea 2 e sebelisa matla nthong ea 1. Boholo ba matla a mabeli boa tšoana empa tataiso ea matla a mabeli e fapane. Matla a mang a bitsoa ketso, matla a mang a bitsoa karabelo.
Letšoao le fosahetseng le bontša tataiso ea matla. Ketso ea F ke e ntle, ha karabelo ea F e le mpe. Sena se bontša hore matla a ketso le karabelo a ka mahlakoreng a fapaneng.
