Term
Electric Field Equation Caused by a Charge 

Definition
E = kQ/r^{2}: where Q is the source charge and r is the distance between the source charge and electric field detector
E = F_{e}/q: where q is the test charge and F_{e} is the electrostatic force
E = V/r: where V is the electric potential 


Term
What is the Direction of the Electric Field? 

Definition
The direction that a positive test charge would move if put in the electric field. 


Term
Electric Potential Energy 

Definition
U=kQq/r: where Q is the source charge, q is the test charge, and k is a constant with a value of 8.99e9 


Term
What Does a Change in the Electric Potential Energy Mean? 

Definition
A decrease in U causes an increase in stability between the charges 


Term
Electric Potential Equation 

Definition
V=U/q: where U is the electric potential energy and q is the test charge
V=kQ/r: where Q is source charge and k is a constant with a value of 8.99e9 


Term
How does a positive test charge spontaneously move? 

Definition
Positive test charge moves from a high electric potential to a low potential which is negative work being done on the test charge leading to a decrease in the electric potential energy 


Term
How does a negative test charge spontaneously move? 

Definition
Negative test charge moves from a low electric potential to a high potential which is negative work being done on the test charge leading to a decreasing electric potential energy
