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

Answer

Explanation:

Step1: Recall energy - unit relationships

Energy has SI unit of joule (J). 1 joule is defined as 1 kg·m²/s². A kilojoule (kJ) is 1000 joules and is also a unit of energy.

Step2: Analyze other units

Newtons (N) is the unit of force ($F = ma$, where $m$ is mass in kg and $a$ is acceleration in m/s², so $1N=1kg\cdot m/s^{2}$). Meters per second - squared (m/s²) is the unit of acceleration.

Answer:

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