Assessment statement Obj Notes5.2.5 Describe the use of ideal ammeters and 2ideal voltmeters.5.2.6 Describe a potential divider. 25.2.7 Explain the use of sensors in potentialdivider circuits.3 Sensors should include light-dependent resistors(LDRs), negative temperature coefficient (NTC)thermistors and strain gauges.5.2.8 Solve problems involving electric circuits. 3 Students should appreciate that many circuitproblems may be solved by regarding the circuitas a potential divider. Students should be awarethat ammeters and voltmeters have their ownresistance.Topic 6: Fields and forces (7 hours)In this topic, students are encouraged to pay attention to the similarities and differences between thefields.TOK: The concept of fields in science is well worth exploring.6.1 Gravitational force and field (2 hours) 6.2 Electric force and field (3 hours)Assessmentstatement6.1.1 StateNewton’suniversal lawof gravitation.6.1.2 Definegravitationalfield strength.6.1.3 Determine thegravitationalfield due toone or morepoint masses.Obj Notes Assessmentstatement6.2.1 State that there aretwo types of electriccharge.6.2.2 State and apply thelaw of conservationof charge.6.2.3 Describe andexplain thedifference in theelectrical propertiesof conductors andinsulators.1 Students should be aware 6.2.4 State Coulomb’sthat the masses in the force law.law are point masses. Theforce between two sphericalmasses whose separationis large compared to theirradii is the same as if thetwo spheres were pointmasses with their massesconcentrated at the centresof the spheres.1 6.2.5 Define electric fieldstrength.3 6.2.6 Determine theelectric field strengthdue to one or morepoint charges.Obj123Notes1 Students should beaware that thecharges in the forcelaw are pointcharges.1 Students shouldunderstand theconcept of a testcharge.3
