Physics 11 Electives – gravitational field, radio waves, electronics

PhysicsElectricity & CircuitsAges 16–17

Three Physics 11 elective topics in one template, switched with the topic parameter. Gravitational field: drag to change a satellite's orbital radius around Earth and see gravitational acceleration g = GM/r², orbital speed, and period, then find the geostationary orbit. Radio wave transmission: watch the audio signal, carrier wave, and the AM- or FM-modulated wave play out over time. Introduction to electronics: a half-wave or full-wave rectifier circuit, with an optional filter capacitor to smooth the ripple in the DC output.
