Answer

Explanation:

Step1: Recall the unit of energy

The standard unit of energy in the SI system is the joule ($J$).

Step2: Analyze the derived unit

Energy can also be expressed in terms of base units. Using the formula for work (W = F\times d) (where (F = ma)), substituting (F=ma) (with (m) in kg, (a) in (m/s^{2})) and (d) in (m)), we get (W=(kg\times m/s^{2})\times m=kg\cdot m^{2}/s^{2}).

Step3: Consider the prefix

Kilojoules ((kJ), where (1kJ = 10^{3}J)) are also a valid unit for energy as they are a multiple of the joule.

Step4: Eliminate non - energy units

Newtons ((N)) are the unit of force ((F = ma), (N=kg\cdot m/s^{2})). Meters per second squared ((m/s^{2})) is the unit of acceleration.

Answer:

joules, kilogram meters²/seconds², kilojoules
