Detailed Analysis of Physical Units:

• Work: Defined as Force $\times$ Displacement, unit is $\text{N}\cdot\text{m}$ (or Joule). (Included).
• Energy: Capacity to do work, dimensionally identical to work, unit is $\text{N}\cdot\text{m}$ (or Joule). (Included).
• Torque: Defined as Force $\times$ Perpendicular distance, unit is strictly $\text{N}\cdot\text{m}$. (Included).
• Power: Rate of doing work, unit is Watt ($\text{J/s} = \text{N}\cdot\text{m/s}$). (Not N-m).
• Momentum: Mass $\times$ Velocity, unit is $\text{kg}\cdot\text{m/s}$ or $\text{N}\cdot\text{s}$. (Not N-m).
