This study guide covers gravitational and electromagnetic forces, focusing on factors influencing electromagnetic force (spatial scale, magnitude of charges, motion of charged objects), comparing and contrasting electric and gravitational forces (similarities and differences), and preparing for the final exam (inverse square law, similarities/differences between forces, factors affecting force strength, conceptual understanding). Example problems and practice questions (multiple-choice and free-response) are included. Key terms: inverse square law, electric force, magnetic force, gravitational force.
