Fun Work Equation Physics

In our everyday language work is related to expenditure of muscular effort but this is not the case in the language of physics.

Work equation physics. Electric field work is the work performed by an electric field on a charged particle in its vicinity. This equation is one form of the work-energy equation and gives us a direct relation between the net work done on a particle and that particles velocity. The magnitude of the force form the formula of work done it is evident that the higher the magnitude of force the work done will be higher and vice-versa.

The change in voltage is defined as the work done per unit charge against the electric fieldIn the case of constant electric field when the movement is directly against the field this can be written. LatextextWDelta textKEfrac12 textmv_textf2-frac12 textmv_texti2latex where v i and v f are the speeds of the particle before and after the application of force and m is the particles mass. In physics we say that a force does work if the application of the force displaces an object in the direction of the forceIn other words work is equivalent to the application of a force over a distance.

There are several special cases that are worth noting. Voltage Difference and Electric Field. First when the force is constant and is parallel to the displacement x the above equation simplifies to.

For the sake of simplicity we will consider the. The electric field performs work on the particle. The force and the displacement are given in the problem statement.

For example F x k x for a spring. The next simplest case is when the force is a linear function of x. For the potential energy the formula.

This energy is now called the kinetic energy of a moving body and its formula was derived directly from Newtons work equation. 422 W F x. In physics we can define energy as the capacity to do work.
