• In order to bring two like charges near each other work must be done.   In order to separate two opposite charges, work must be done.  Remember that whenever work gets done, energy changes form.

• As the monkey does work on the positive charge, he increases the energy of that charge.  The closer he brings it, the more electrical potential energy it has.

Multiple Choice

In order for two like charges to be near each other

• Work must be done which changes the energy, resulting in high PE

• Work must be done which changes the energy, resulting in low PE

• Energy is not changed, so there is no PE

Electricity

Electrical potential energy

• The potential energy of an electric charge depends on its

position in an electric field.

• The electrical potential energy of a moving charge

decreases because the electric field does work on the
charge.

​ electrical potential energy: the ability to move an

​electric charge from one point to another

Multiple Choice

The ability to move an electric charge from one point to another is

• electrical kinetic energy

• potential energy

• electric potential energy

• kinetic energy

Multiple Select

An electrical charge could move another electrical charge because (more than one answer)

• They are different charges and they are attracting each other

• They are the same charge and repelling each other

• They are different charges and they are repelling each other

• They are the same charge and attracting each other

Electric Potential Difference

• Potential difference is measured in volts.

– potential difference:the voltage difference in

potential between two points in a circuit

– For a repulsive force electrical potential energy

increases as the charges move closer to each other.

• The volt, V, is equivalent to one joule per coulomb

(1 J/C).

• Potential difference is often called voltage.

Multiple Choice

Another name for potential difference is

• work

• electric potential energy

• potential energy

• voltage

Multiple Choice

Potential difference is measured in

• Joules

• Volts

• Amps

• Coulombs
