Electric field acceleration

Definition

Electric field acceleration refers to the increase in velocity of charged particles as they move through an electric field. The force exerted by the electric field on these charged particles causes them to gain kinetic energy, which is fundamental in various applications, such as particle accelerators used in research and the underlying principles of accelerator physics.
