the concept of energy can be calculated in multiple ways. which units are used for energy? check all that apply. \n□ joules\n□ kilogram meters²/seconds²\n□ newtons\n□ kilojoules\n□ meters/seconds²

Answer

Explanation:

Step1: Recall energy - unit relationships

The SI unit of energy is the joule (J). 1 joule is defined as 1 kilogram - meter²/second² ($1\ J = 1\ kg\cdot m^{2}/s^{2}$). A kilojoule (kJ) is a multiple of the joule where $1\ kJ= 1000\ J$.

Step2: Analyze other units

Newtons (N) are units of force ($F = ma$, where $m$ is mass in kg and $a$ is acceleration in $m/s^{2}$, so $1\ N=1\ kg\cdot m/s^{2}$). Meters/second² ($m/s^{2}$) are units of acceleration.

Answer:

A. joules, B. kilogram meters²/seconds², D. kilojoules
