How does mass affect gravity? How does distance affect gravity? Where is there more gravity in space- Jupiter or the moon? Magnetism Where is the magnetic field strongest? What happens to like poles? What happens to opposite poles? What is the main difference between a permanent magnet and an electromagnet? How does distance affect magnetic field strength? What causes magnetic poles?-/ J = 100 70 8/9 = 95% 7/9= 90% 6/9 = 85% 5/9 = 80% 4/9 = 75% 3/9 = 70% s to Study Electric Fields Where are electric fields the strongest? What happens to opposite charges? What happens to like charges? How can we create an electric charge? Electricity What are the 2 types of circuits? What type of circuit is the most useful? How are electric fields and electricity different? What types of charge is electric current? . Examples of conductors and insulators
