Answer

$N*m/s$

Work Step by Step

Power is equal to $Work/time$. We know that Work is equal to $Force*Distance$. The units for Force are Newtons (N), and the units for distance are meters (m). Therefore, the units for work are $N*m$. Additionally, the SI Unit for time is the second. If we combine all of these, we get that power has the base SI units of $N*m/s$. This can be further simplified to Joules per second (J/s), also known as the Watt.
