One joule is equal to the work done by the force of a single newton when its points of application travels through a distance of 1 meter in the same direction as the force, so it is also equivalent to 1 watt-second or 0.2390 calories. The joule is named after James Prescott Joule, and it is a standard unit of work or energy in the International System of Units.
Know MoreOne Joule represents the work it takes to move an object one meter. It is a unit of measurement for energy in the International Standard of Units (SI). One joule is correlated with one Newton force, as the joule is the engine behind the force that moves an object over one meter.
The standard symbol of one joule is an apple, as its weight is equal to one Newton. At a height of one meter, the apple is exerting the energy of one joule. While on the floor, gravity is exerting the energy against the apple. It is one joule of energy that is needed to lift the apple one meter in height. So the energy of one joule is exerted against the one Newton in order to lift the apple to one meter.

Full Answer >An electric force is an attractive or repulsive force between two charged objects. Electric forces are attractive when two objects have opposite charges and repulsive when two objects have like charges. Electric forces are different from magnetic forces, although the two are strongly related.
Full Answer >A static force refers to a constant force applied to a stationary object. A static force is too weak to move an object because it is being countered by equally strong opposite forces.
Full Answer >Electromotive force is the difference in electrical potential between two points that compels electricity to flow to an area of lower potential in order to equalize charge. According to the HyperPhysics website, the force is measured in volts and frequently abbreviated as "emf."
