What does 1 joule represent in terms of mechanical energy?

One joule is the energy transferred when a force of one newton moves an object one meter; it represents mechanical work or gravitational potential energy.

How is kilowatt-second related to kilojoule?

One kilowatt-second is equivalent to one kilojoule, meaning 1 kW·s equals 1000 joules.

Why is it important to distinguish kilowatt-seconds from kilowatt-hours?

Because kilowatt-hours differ from kilowatt-seconds by a factor of 3600 seconds per hour, confusing these can lead to incorrect energy calculations.
