A Coconut With A High Potential....
a: Electric field ~
b: moving a coconut off the ground
What: "A gravitational analogy can be used to explain electric potential difference. Moving a positive charge against the direction of an electric field is like moving a coconut upwards within Earth's gravitational field. Both movements require work down by an external force. This work would in turn increase the potential energy of the object."
