If the work done by an electric field is N, then the work done by me will be negative N? Perhaps this applies if I move a charge against the field lines, but what if I move in the same direction?
The sign convention for work is a set of rules used to determine the sign (positive or negative) of work done on an object by an external force. It is based on the direction of the force and the direction of the displacement of the object.
The sign convention for work is important because it helps us determine whether work is being done on an object or by an object. It also helps us understand the direction of energy transfer in a system.
The sign convention for work is determined by the direction of the force and the direction of the displacement. If the force and displacement are in the same direction, work is considered positive. If they are in opposite directions, work is considered negative.
A positive work value indicates that work is being done on an object, meaning energy is being transferred to the object. This could result in an increase in the object's kinetic energy, potential energy, or both.
A negative work value indicates that work is being done by an object, meaning energy is being transferred from the object. This could result in a decrease in the object's kinetic energy, potential energy, or both.
