Energía (física)

Energy exists in various forms such as electrical, thermal, kinetic, and potential. It can be transformed but not created or destroyed, adhering to the law of conservation. The joule is the standard unit of energy, defined as the work done by a force of one Newton to move an object one meter in the force's direction.

How is a joule defined in terms of work done?

• Work done by a force of one Newton to displace an object 1 kilometer

• Work done by a force of one Watt to displace an object 1 meter

• Work done by a force of one Joule to displace an object 1 meter

• Work done by a force of one Newton to displace an object 1 meter
