They investigate electromagnetic interactions and apply this knowledge to understand the operation of direct cur ent motors, direct current (DC) and alternating current (AC) generators, transformers, and AC power distribution systems. Students also the production of electromagnetic Learning outcomes By the end of this unit, students: understand that motion in gravitational, electric and magnetic fields can be explained using Newton’s Laws of Motion understand how the electromagnetic wave model explains the production and propagation of electromagnetic waves across the electromagneticsps understand transformations and transfer of energy in electromagnetic devi as wel as transformations and transfer of energy as ociated with motion in gravitational, electric and magnetic fields understand how models and theories have developed over time, and the ways in which physi nce knowledge and as ociated technologies interact with ial, economic, cultural and ethical considerations nce inquiry skills to d conduct, analyse and evaluat investigations into uniform circular motion, projectile motion, satellite motion gravitational and electromagnetic phenomena, and to communicate use algebraic and graphical representations to calculate, analyse and ict measurable quantiti to motion, gravitational ef ects and electromagnetic phenomena luate, with ref gravity and ctromagnetic phenomena and associated technologies, and justify evaluations understanding using qualitative and quantitative representations in appropriate modes and genres. WACE Physics ATAR Cours‘Government Year 12 Sylubus © SchoolAsa,Curriculum and Standerdsby permission Austad, of Westem 2017; reproduced Gravity is the force that drives the universe. It was gravity that first caused particles, to coalesce into atoms, and atoms to congregate into nebulas, planets and stars.
An understanding of gravity is fundamental to understanding the universe. This chapter centres on Newton's law of universal gravitation. This will be used to predict the size of the force experienced by an object at various locations on the Earth and other planets. It will also be used to develop the idea of a gravitational field and to refine the understanding of gravitational potential energy developed in Year 11.
Since the field concept is also used to describe other basic forces such as electromagnetism and the strong and weak nuclear forces, this will provide an important foundation for further areas of study later in this unit.
