U = kQ1Q2/R
2. What does electric potential stand for?
Voltage
3. What is Electrostatic Potential?
Voltage
4. What is the work done ON a charge?
W=Q∆V
5. 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.
6. What is potential difference?
Voltage
7. In a constant electric field what is voltage equal to?
V = Ed
8. What charge has a higher potential?
Positive
9. What charge has a lower potential?
Negative
10. What is the work done on a charge equal to?
W = Q∆V = Fd = ∆KE
11. 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)
12. When the motion of a charge opposes the field what is the sign of the work?
Positive
13. In what direction does a charge doing negative work travel?
Along the field lines.
14. How do you calculate the total electrostatic potential ENERGY?
U=kQ1Q2/r And just keep summing them, keeping track of their parts.
15. What is the work done? In both KE and delta V
• q∆V
• (1/2)mv2 - (1/2)mv2
16. What is electrostatic potential (voltage) in a uniform electric field?
V=Ed
17. What is the electric potential of a point charge or sphere?
V = kQ/r
18. What is the net/total electric potential?
∑ k(Q/r)
19. What is the electrostatic potential energy?
U kqQ/r
20. Does electrostatic potential energy have a sign?
Yes, from the contributing charges.
