Electric Fields
Flashcards do conjunto (5)
- 1Define Electric Field StrengthElectric field strength (at a point in space) is the force per unit positive charge
- 2State that electric fields are created by electric chargesElectric charges exert forces on each other when they are
a distant apart. An electric field is a region of space where
a stationary charge experiences a force - 3Explain the effect of a uniform electric field on the motion of a charged particleIf E is uniform, then the acceleration of the charged particle is constant. If the particle has a positive charge, then its acceleration is in the direction of the electric field.
If the particle has negative charge, then its acceleration is in the direction opposite the electric field - 4Describe how electric field lines represent an electric fieldThe direction of the electric field is defined as the direction in which a positive charge would move if it were free to do so. So the lines of force can be drawn with arrows that go from positive to negative
- 5Describe the similarities and differences between the gravitational fields of point masses and the electric fields of point charges
