Units in Kinematics

The unit for distance is meter.

$m$

The units for velocity are meters per second.

$\frac{m}{s}$

Acceleration is change in velocity per time.

$a=\frac{\frac{m}{s}}{s}=\frac{m}{s^{2}}$

Force is mass times acceleration

$N=kg \frac{m}{s^{2}}=\frac{kg m}{s^{2}}$

Energy is force times distance

$J = N m =\frac{kg m^{2}}{s^{2}}$

Power is energy per unit time.

$P=J/t=\frac{Nm}{s} =\frac{kg m^{2}}{s^{3}}$
