## Electric Fields

Summary

The content provides an in-depth exploration of electric fields, focusing on their vector nature, equations to calculate their magnitude, and practical applications in solving problems.

- Electric fields are vectors because they have both magnitude and direction.
- The magnitude of an electric field can be calculated using the equation: electric field equals voltage divided by separation (volt per meter) or as a force over a charge (Newton per Coulomb).
- For a point charge, the electric field can be represented by the equation kq over r squared, indicating how the field radiates from the charge.
- The direction of an electric field always goes from positive to negative, with field lines illustrating the path a positive test charge would take.
- Through a practical example involving a charged ping-pong ball, the process of calculating acceleration in an electric field is demonstrated, emphasizing the importance of unit conversion and equation manipulation.
