This AP Physics 2 study guide covers electric fields and electric field strength. It explains how electric fields are created by charges, visualized with field lines, and how their strength varies with distance. Key formulas like E = F/q and E = kQ/r^2 are explained and applied through multiple-choice and free-response practice questions involving point charges and parallel plates. The guide emphasizes understanding field line diagrams, calculating field strength, and connecting electric fields to concepts like force, potential, and energy.
