Electric fields

• What are electric fields described as in the material?

  Much less green and more shocking
• How is an electric field created?

  By any electrically charged object
• What is the region around a charged object called?

  Electric field
• What happens if a second charged object is placed inside an electric field?

  A force is exerted on both charges
• How does the strength of an electric field change with distance?

  Stronger when closer to the object
• How can you visualize an electric field around an object?

  By using field lines
• What are the characteristics of electric field lines?

  • Go from positive to negative charges
  • Always at a right angle to the surface
  • Closer lines indicate a stronger field
• What happens when two charged objects interact in an electric field?

  They attract or repel each other
• What do parallel charged plates create?

  A uniform electric field
• What is the relationship between the strength and direction of an electric field?

  Same anywhere between the two plates
• What are the effects of electric fields on charged objects?

  • Exert forces on each other
  • Cause attraction or repulsion
  • Influence motion of charged particles
• What do electric fields cause between charged objects?

  Electrostatic forces
• How do electric field lines behave when they are close together?

  Indicate a stronger electric field
• What is the effect of distance on electric field strength?

  It decreases as distance increases
• What are the properties of electric fields between two charged plates?

  • Uniform strength
  • Parallel lines
  • Direction from positive to negative
• What happens to electric field lines when they are drawn from positive to negative charges?

  They indicate the direction of the field
• What is the significance of the angle of electric field lines to the surface?

  Always at a right angle
• How do electric fields interact with charged objects placed in them?

  They exert forces that attract or repel
• What is the result of two charged objects being placed in the same electric field?

  They interact with electrostatic forces
• What happens to the electric field strength as you move away from a charged object?

  It decreases with distance
• How do electric fields behave between two oppositely charged plates?

  They create a uniform field
• What do electric field lines represent?

  The direction and strength of the field
• What is the effect of the distance between two charged objects on their interaction?

  Closer objects experience stronger forces
• How do electric fields influence the behavior of charged particles?

  They determine the motion and interaction
• What is the relationship between electric field strength and the distance from the charge?

  Inversely proportional
• What happens to electric field lines when they are drawn closer together?

  Indicates a stronger electric field
• How do electric fields behave when two charged objects are placed in opposite directions?

  They repel each other
• What is the effect of electric fields on charged objects?

  They exert forces on each other
• How do electric fields interact with neutral objects?

  They induce polarization
• What is the significance of the direction of electric field lines?

  Indicates the direction of force on a positive charge
