In this unit students explore the importance of energy in explaining and describing the physical world. They examine the production of electricity and its delivery to homes. Students consider the field model as a construct that has enabled an understanding of why objects move when they are not apparently in contact with other objects. Applications of concepts related to fields include the transmission of electricity over large distances and the design and operation of particle accelerators. They explore the interactions, effects and applications of gravitational, electric and magnetic fields. Students use Newton's laws to investigate motion in one and two dimensions, and are introduced to Einstein's theories to explain the motion of very fast objects. They consider how developing technologies can challenge existing explanations of the physical world, requiring a review of conceptual models and theories. Students design and undertake investigations involving at least two continuous independent variables.

This unit is delivered in Year 12.

Assessment

Assessment tasks will be designed to reinforce and extend knowledge in accordance with each unit's learning outcomes, including the setting of practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following knowledge: Outcome 1 On completion of this unit the student should be able to analyse gravitational, electric and magnetic fields, and use these to explain the operation of motors and particle accelerators and the orbits of satellites. Outcome 2 On completion of this unit the student should be able to analyse and evaluate an electricity generation and distribution system. Outcome 3 On completion of this unit the student should be able to investigate motion and related energy transformations experimentally, analyse motion using Newton's laws of motion in one and two dimensions, and explain the motion of objects moving at very large speeds using Einstein's theory of special relativity.Assessment will follow the requirements set out in the VCE Physics Study Guide: SCHOOL-BASED ASSESSMENT 1. Satisfactory completion The award of satisfactory completion for a unit is based on whether the student has demonstrated the set of outcomes specified for the unit. A variety of assessment tasks will provide a range of opportunities for students to demonstrate the key knowledge and key skills in the outcomes. 2. Assessment of levels of achievement The student's level of achievement in Unit 3 will be determined by School-assessed Coursework (SAC). SAC will be completed mainly in class and within a limited time-frame. SAC for Unit 3 will contribute 21 per cent to the study score. SAC for Unit 4 will contribute 19 per cent to the study score (PH034 Physics 4). Practical work is a central component of learning and assessment. As a guide, between 3½ and 5 hours of class time should be devoted to student practical work and investigations for each of Areas of Study 1, 2 and 3. EXTERNAL ASSESSMENT The level of achievement for Units 3 and 4 is also assessed by an end-of-year examination, which will contribute 60 per cent to the study score.
