Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time.
5 gru 2018 · SI unit of work is ‘joule’ or ‘J’. 1 joule = 1 newton x 1 metre or 1 J = 1 Nm 1 joule is the amount of work done when 1 newton of force acting on a body displaces it through 1 metre. 5. CGS unit of work is ‘erg’. 1 joule = 107 erg or 1 erg = 10-7 joule

16 kwi 2024 · What is SI Unit of Work. Work is measured in Joule. 1 Joule = 1 Newton Meter. 1 J = 1Nm. Explantion. Since Force is measured in Newton (N) Distance/Displacement is measured in Meter (m) Work done by 1 Newton of Force to produce displacement of 1 meter = 1 Joule. Work = Force × Distance.
23 sty 2024 · Work = Force x Displacement Unit of workdone = Joule = Newton x metre 1 Joule work is said to be done when 1 Newton force is applied on an object and it shows the displacement by 1 meter. Energy The capacity of a body to do work is called the energy of the body.
If F = 1 N and d = 1 m then the work done by the force will be 1 N m. Here the unit of work is Newton meter (N m) or joule (J). Thus 1 J is the amount of work done on an object when a force of 1 N displaces it by 1 m along the line of action of the force.
Work done on an object is defined as the product of the magnitude of the force acting on the body and the displacement in the direction of the force. W = F.s. The SI unit of force is Newton. If a force acting on a body causes no displacement, the work done is 0. For example, pushing a wall.
