As you know Joule measures work and energy. One joule is the amount of work done when a force of one newton acts on an object that moves one meter in the direction of the force. The joule is used to measure all forms of energy, including heat, electrical, and mechanical energy. One joule per second is called a watt, a unit of electrical and mechanical power. You need force to move an object.
Force is measured in newtons.
When you move a book 10 meters that weights 1 kilogram you do 10 newton-meters of work. A newton-meter is also called a joule, the unit used to measure energy and work. Say someone is using a force of 20 newtons to move a shopping cart 5 meters. To find this out you multiply force by distance or you multiply how many newtons of force by how many meters traveled.
