Kilowatt-hour is the unit of : A. Energy B. Power C. Force D. Momentum

Power is the rate at which energy is used or transferred. It is measured in watts, where 1 watt is equal to 1 joule per second.

Force is the interaction between two objects that causes them to accelerate. It is measured in newtons, where 1 newton is equal to the force required to accelerate a mass of 1 kilogram at a rate of 1 meter per second squared.

Momentum is the product of an object’s mass and velocity. It is measured in kilogram-meters per second.

In summary, a kilowatt-hour is a unit of energy, not power, force, or momentum.
