The unit Joule is named in honour of the renowned scientist James Prescott Joule.Analog Devices is in the process of updating our website. We can define the unit Joule as the amount of energy transferred when a force of 1 Newton is applied on an object for a length of 1 meter. Since we take the dot product, the resultant energy is a scalar. Moreover, we can prove that the work done (i.e: the energy transferred) is F.x. Since F = d(mv)/dt, by integrating both sides with respect to dx, we can obtain the result F.x =(mv 2)/2. The initial kinetic energy of the system is zero and assuming the object takes a velocity v after the distance x the final kinetic energy is (mv 2)/2. Moreover, we can give energy to a system in several ways either by doing work on the system or directly as an energy transfer like heating the system.įor instance, imagine a solid mass of m kg on a frictionless flat, horizontal surface is given a net force F over a distance x. Kinetic energy, thermal energy and potential energy are to name a few. But we can calculate it by measuring external properties. Energy is not a directly observable quantity. In this sense, energy is the mechanism behind an activity. The term “energy” comes from the Greek word “energeia”, which means operation or activity. To understand what a Joule is, a proper understanding of the concepts of energy and work are necessary. The unit Newton got its name after the eminent scientist Sir. accelerating an object with unit mass, by a unit velocity, on unit time). To eliminate the proportionality constant, Newton is defined as the force required to change the velocity of an object with a mass of 1 kilogram, by 1 meter per second, in 1 second. Net force =constant X momentum change / timeįorce has the basic units kg m/s 2. According to Newton’s second law of motion, the net force acting on an object is proportional to the rate of change of linear momentum of that object. Since the mass is a scalar, and the velocity is a vector, the linear momentum is also a vector, which has the same direction as the velocity. The linear momentum of an object is equal to the mass of the object multiplied by the velocity of the object. To understand what a Newton is, one must first understand the concept of force and linear momentum. Side by Side Comparison – Newton vs Joule in Tabular Form The basic difference between Newton and Joule is their applications. These units are extremely important, and a sound understanding of them is necessary. Joule and Newton are two units that are very useful in the SI unit system. The key difference between Newton and joule is that Newton is a unit that measures force, while Joule is a unit that measures energy.
