# Summary
|
|
* Change in electric potential energy for charge moving between 2 potentials $\Delta U_E=q\Delta V$ (J)
|
|
* q can be positive or negative. $\Delta V=V_{final}-V_{initial}$.
|
|
* Energy is conserved: $\Delta K=-\Delta U_E$
|
|
* Positive charges speed up moving towards lower potential. Negative charges speed up moving towards higher potential.
|
|
* Electric field points towards decreasing potential.
|
|
* For particle starting at rest, kinetic energy gained equals magnitude of $q\Delta V$, lets you solve for final speed. |
