Aug 7, 2024 · What is a Joule? A Joule 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 simpler terms, a Joule represents the energy required to perform a specific action, such as lifting a small apple one meter up in the air.

The meaning of JOULE is a unit of work or energy equal to the work done by a force of one newton acting through a distance of one meter.

1 J is defined as the work done for one ampere of electric current to pass through an electric circuit with external resistance equivalent to one ohm per second. It can be illustrated by the following equations:

Not to be confused with Joules per second. The joule-second (symbol J⋅s or J s) is the unit of action and of angular momentum in the International System of Units (SI) equal to the product of an SI derived unit, the joule (J), and an SI base unit, the second (s). [1] . The joule-second is a unit of action or of angular momentum.

May 22, 2019 · Joule is a derived unit of energy. 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 metre. One joule in everyday life and in science corresponds to approximately: The kinetic energy of an object with mass 1 kg moving at √2 ≈ 1.4 m/s.

Mar 7, 2019 · Learn the definition of a joule, a basic unit of energy used in chemistry, chemical engineering, and physics, plus learn what a joule is equal to.

Jul 12, 2007 · What is a Joule? The joule (J) is the unit of measure for energy used in the International System of Units (SI), and the one accepted in scientific circles. The unit is used in all equations and calculations involving energy.

One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force. To use a real-life example, gravity exerts about 1 newton of force on the average apple. To raise an apple one meter in the air, you must use one joule of kinetic energy.
