what is the equation for work done. The force and the displacement are given in the problem statement. Since Force is measured in Newton N DistanceDisplacement is measured in Meter m Work done by 1 Newton of Force to produce displacement of 1 meter 1 Joule.
If the distance moved d is not in the direction of the electric field the work expression involves the scalar product. We know that the scalar product of two vectors A and B where A makes an angle th with B is given by A. 1 J 1Nm.
Work is measured in Joule.
DefinitionSummary Work is a measure of change of energy. The cosine of zero is. It is the work done by a force of 1 newton when it displaces a body through 1 metre. Work Force Distance.
