Which unit is NOT used to measure energy transfer?

• A. Joule (J)
• B. Kilowatt-hour (kWh)
• C. Kilojoule (kJ)
• D. Newton (N)

Answer: (D)

The unit that is not used to measure energy transfer is the Newton (N). Newton is a unit of force, not energy. It measures the amount of force required to accelerate a one-kilogram mass by one meter per second squared. In contrast, Joules, kilowatt-hours, and kilojoules are all units specifically related to energy transfer. Joules are the standard unit of energy in the International System of Units (SI), while kilowatt-hours are used primarily in the context of electrical energy consumption, often seen in utility billing. Kilojoules, being a multiple of Joules, also measures energy in various contexts, including food energy. Therefore, the Newton stands out as it pertains to force rather than energy measurement.
