P'ikwachiy nisqaqa ( kastilla simipi : aceleracion ) nisqaqa imappas utqa kayninpa huk mit'api mirayninmi, utqa kay pachamanmi . Kaymi kuskanchaku pikwachiy minuywa:

${\displaystyle a={\frac {v-v_{0}}{t-t_{0}}}={\frac {\Delta v}{\Delta t}}}$

Kaymi kuskanchaku pikwachiy minuywa:

${\displaystyle \mathbf {a} ={\frac {d\mathbf {v} }{dt}}}$

Utqa tupuqa kaymi:

• Mitru t'asra sikunduman

${\displaystyle {\frac {m}{s^{2}}}}$ icha ${\displaystyle {m}{s^{-2}}\,}$
