# Cahnge in potential difference of moving electron

 P: 7 Yes, i understand the electron is accelerating. obviously, its speed increases, so its kinetic energy also increases. I understand all these concepts. I don't know which equations to use. That is where I'm stuck. All the equations I can think of using velocity have time or distance variable, which i can't use. The only one I know is K = 1/2mv^2 So would I do $$\Delta$$K = 1/2mv2^2 - 1/2mv1^2 and since $$\Delta$$K = - $$\Delta$$UE I can then use $$\Delta$$V = $$\Delta$$U/e to get the potential difference??? Is $$\Delta$$V potential difference or just potential or electric potential?? that is one area I am confused. Thank you
