Question 91315 • WA-Physical Science B
Energy is measured in joules (J), and 1 joule equals 1 kilogram meter squared per second squared (kg·m²/s²). A kilojoule is also an energy unit: 1 kJ = 1,000 J. Newtons measure force, while meters per second squared measure acceleration, so neither is an energy unit.
