Defining electric potential energy and potential

• How does the electric potential energy of a positive charge change when it moves towards another positive charge?

  It decreases as energy is released
• How does electric potential differ from electric field strength?

  Electric potential focuses on energy per charge
• How do electric potential and electric field strength relate to each other?

  Electric potential is energy-focused, field strength is force-focused
• What does electric potential (V) represent in an electric field?

  Energy per unit charge
• What does the electric field describe?

  Force per unit charge
• If an electric field strength is 5 N/C, what force acts on a 1C charge?

  5 N of force
• What does electric potential energy indicate about a charge?

  It indicates energy based on its location
• What happens to a positive charge's electric potential energy when it moves away from another positive charge?

  It increases as the charge moves away
• In what unit is electric potential measured?

  Volts (V)
• What does electric field strength show?

  Force per charge
• How can we visualize the relationship between electric potential and electric potential energy?

  • Electric potential (V) is like height per step.
  • Charge (q) is the number of steps climbed.
  • More steps (larger charge) lead to higher potential energy.
• What does electric potential represent?

  Energy per unit charge
• What does electric potential measure?

  Energy per unit charge at each point
• What does the volt indicate in terms of energy?

  Energy gained or lost per coulomb of charge
• How does an electric field affect a charge?

  It applies a force on a charge
• What are the units of electric field?

  Newtons per coulomb (N/C)
• What does a potential of 10 V indicate for a charge?

  It has 10J of energy at that location
• How do electric field and electric potential differ in their focus?

  Electric field focuses on force; potential on energy
• What does a higher electric potential indicate?

  A charge has more energy if placed there
• If the electric potential (V) is 10 V and the charge (q) is 2 C, what is the electric potential energy (EP)?

  20 J
• How do you calculate electric potential energy (EP) of a charge (q)?

  EP = Vq
