Physics 2.4 Demonstrate understanding of mechanics
Achievement criteria
The level of performance that you will gain will be determined by the complexity of the questions, and how you answer them. You need to be able to describe and explain wave phenomena and use mathematical methods to solve problems.
Minor errors (computational or transcription) will not be penalised if the process used to determine the solution is clearly indicated and is valid.
Achievement
Make sure you can:
- identify or describe aspects of phenomena, concepts, or principles
- approach the question from a physical perspective when describing the relevant physics concept
- solve straightforward problems which involve a single-step process
- draw simple, labelled diagrams.
Achievement with Merit
Make sure you can:
- give accurate explanations in terms of phenomena, concepts, principles, and/or relationships
- approach the question from a physical perspective when explaining the relevant physics concept
- solve problems that may involve using a complex formula or rearrangement or some deduction as to the relevant concept or principle involved
- draw accurate, labelled diagrams
- state answers to the correct significant figures and avoid rounding-off prematurely.
Achievement with Excellence
Make sure you can:
- meet criteria for Merit
- give concise and accurate explanations that show clear understanding in terms of phenomena, concepts, principles, and/or relationships. Your answers will typically have minimal irrelevancies. In other words, you cannot include any explanations that are not relevant. Do not guess!
- approach the question from a physical perspective linking your explanations to the relevant physics concept
- solve complex problems, which will involve more than one process and concept.
