Electric potential energy definition doubt?

SUMMARY

The electric potential energy of a charge \( q \) in an electric field is defined as the work done by an external force in moving the charge from infinity to a specific point in the field without any acceleration. This definition emphasizes that the charge must not experience any change in kinetic energy during the process, ensuring that the work done directly translates to a change in potential energy. The discussion clarifies that any acceleration would alter the kinetic energy, complicating the relationship between work and potential energy.

Electric potential energy of a charge q at a point in an electric field due to any charge configuration as the work done by the external force in bringing the charge q from infinity to that point without any acceleration..


In this definition, why charge is moved without any acceleration?
 
Physics news on Phys.org
Acceleration changes the velocity, and therefore also the kinetic energy. The work done on the charge equals the change in potential energy only if the change in kinetic energy is zero.
