The seven items that comprise Système Internationale d'Unitès do not include force or energy.

However, the unit for force, the Newton, by definition, utilizes the official SI units kilograms, meters, and seconds.



Likewise, the unit for energy, the Joule, by definition, utilizes the official SI units kilograms, meters, and seconds.

You may notice that the units for force correspond to mass multiplied by acceleration, and that the units for energy correspond to force multiplied by distance. When you study physics you will explore this further.
