which may move a body or stop a moving body or change its speed or change its direction or may even change its shape and size. Force is an external effort in the form of stretching, compressing, pushing, pulling, etc. This is all from this article on the Definition, formula and calculation of work done in Physics. To understand work, we need to have a clear idea about the concept of force and the concept of displacement. So, the work done is the phenomena in which the mechanical energy is transferred form an external system to the target body. The work done on a body is stored as the potential energy inside the body and to do a work, a system needs to have some energy. However, the dimensional formula and units are same for these two quantities. Is Energy and work done are same in Physics?Įnergy and work done are not same in Physics in terms of physical quantity. If a particle moves perpendicular direction to the applied force, then the work done becomes zero.For example: If an object starts its journey from a point and finishes it at the same point after travelling a distance, then its displacement is zero. If the displacement of the object becomes zero then the work done also becomes zero.There are two conditions at which the work done by an applied force becomes zero. At what condition the work done by the applied force becomes zero? Here also you need to know the values of above three quantities.

If a net force F displaces a body by r in the direction of applied force, then the equation of work done is, \color W = F.rcos\theta to calculate it.Īgain, one can find the amount of work done by using the work done calculator directly. A beautiful, free online scientific calculator with advanced features for evaluating percentages, fractions, exponential functions, logarithms, trigonometry. Work done is the multiplication between the net applied force and the displacement of the object. It is not essential that the body always moves in the same direction of applied force. So, it is important that the body must have some displacement. This type of work is nothing but the mechanical work. In Physics, when a body moves some distance due to the application of net external force, then it is said that the external force have done a work. Is work done energy? Definition of work done in Physics.At what condition does the work done become zero?.In this article we are going to explain the concept, formula and calculation of work done in Physics or science. But, the Work done in Physics is different from the work we know in our daily life. Physics also says that some external energy is required to do a work. Work is one of the popular words in our daily life.
