What is The Electric Potential energy?

U = kQ₁Q₂/R
What does electric potential stand for?

Voltage
What is Electrostatic Potential?

Voltage
What is the work done ON a charge?

W=Q∆V
How do you find the total potential of a point between two charges?

V = kQ/R + kQ/R …. Sum of Volts, each their own R distance away from point.
What is potential difference?

Voltage
In a constant electric field what is voltage equal to?

V = Ed
What charge has a higher potential?

Positive
What charge has a lower potential?

Negative
What is the work done on a charge equal to?

W = Q∆V = Fd = ∆KE
How do you determine the sign of Work?
- Observing the direction of motion in comparison to the electric field.
- When motion opposes field, positive work. (Up Stairs)
- When motion moves along field, negative work. (Gravity)
When the motion of a charge opposes the field what is the sign of the work?

Positive
In what direction does a charge doing negative work travel?

Along the field lines.
How do you calculate the total electrostatic potential ENERGY?

U=kQ₁Q₂/r And just keep summing them, keeping track of their parts.
What is the work done? In both KE and delta V
- q∆V
- (1/2)mv² - (1/2)mv²
What is electrostatic potential (voltage) in a uniform electric field?

V=Ed
What is the electric potential of a point charge or sphere?

V = kQ/r
What is the net/total electric potential?

∑ k(Q/r)
What is the electrostatic potential energy?

U kqQ/r
Does electrostatic potential energy have a sign?

Yes, from the contributing charges.
