How is joule defined

The joule (symbol: J) is the SI derived unit of energy, work, or amount of heat. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter.

The joule (symbol: J) is a unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter in the direction of the force. Mathematically, it can be expressed as:

1 J = 1 N * 1 m

where N represents newton and m represents meter.

The joule is the unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter.

To understand how the joule is defined, we need to break it down into its constituent units. In SI, work is defined as the product of force and displacement. Force is measured in newtons (N), and displacement is measured in meters (m). Therefore, the unit of work in SI is the newton-meter (N·m). This is also known as the joule (J), which is the accepted unit for energy.

The definition of the joule tells us that if we exert a force of one newton over a distance of one meter, then we have done one joule of work or produced one joule of energy.

In summary, the joule is defined as the work done when a force of one newton is applied over a distance of one meter.
