Kecepatan adalah besarnya perpindahan pada selang waktu tertentu.

Hitung perpindahan benda di sumbu x dan di sumbu y :

increment straight x equals 8 minus 0 equals 8 space straight m increment straight y equals 6 minus 0 equals 6 space straight m

Hitung besar perpindahan benda :

increment straight s equals square root of increment straight x squared plus increment straight y squared end root equals square root of left parenthesis 8 right parenthesis squared plus left parenthesis 6 right parenthesis squared end root space equals space square root of 100 equals 10 space straight m

Maka kecepatan benda :

straight v space equals space fraction numerator increment straight s over denominator straight t end fraction straight v space equals fraction numerator 10 over denominator 2 plus 3 end fraction space equals space 10 over 5 space equals space 2 space straight m divided by straight s
