Can you explain each of these out loud, without looking? If not, re-read that lesson.
- Gravitational Fields: Mapping g fields with F = GmM/r² and linking field strength to potential.
- Electric Fields: Using E = F/Q and E = V/d for point charges and uniform fields.
- Magnetic Fields: Finding field patterns and the force F = BIl on current-carrying wires.
- Potentials and Equipotentials: Reading field strength from equipotential spacing and calculating work done.
- Read each lesson's summary and re-do its practice questions from memory.
