(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

As an electron moves through a region of space, its speed increases from 2.2e^6 m/s to 6.0e^6 m/s. The electric force is the only force acting on the electron.

a) Did the electron move to a higher potential or a lower potential?

b)Across what potential difference did the electron travel?

2. Relevant equations

well for part b, i'm not even sure what to use.

K = 1/2mv^2

U=q x V

3. The attempt at a solution

Well i know part a), the electron moves to a higher potential.

I really don't know how to solve this since the distance or time is not given. And I may be confused as to the difference between potential difference and electric potential. I don't know where to start!
