# Physics

## SUBJECT overview

We follow the AQA syllabus in Physics. The course is split in three units at both AS and A2 stages.

Learners will take their terminal examination in June. They will study the following units at AS:

•Unit 1: Particles, Quantum Phenomena and Electricity

•Unit 2: Mechanics, Materials and Waves

•Unit 3: Investigative and Practical Skills. (20% of total AS marks, 10% of total A Level marks)

The learners will study the following units during the A2 units taking their terminal examinations in June:

•Unit 4: Fields and Further Mechanics

•Unit 5: This unit comprises two sections

◦Section A: Nuclear and Thermal Physics

◦Section B: Option Units

•Unit 6: Investigative and Practical Skills. (10% of the total A Level marks)

## unit overview - spring term

 Capacitors, Magnetic fields, and Electromagnetic induction 23: Capacitors, 24 Magnetic fields, 25: EM induction Skills After carrying out the practical tasks in this topic, students will gain the following skills Required Practical 11: Investigating the charging and discharging of capacitors through a resistor. ATb. Use appropriate digital instruments, including electrical multimeters, to obtain a range of measurements (to include time, voltage). ATd. Use stopwatch for timing. ATf. Correctly construct circuits from circuit diagrams using DC power supplies, cells, and a range of circuit components, including those where polarity is important. ATg. Design, construct and check circuits using DC power supplies, cells, and a range of circuit components. After carrying out the practical tasks in this topic, students will gain the following skills Required Practical 10: Investigate how the force on a wire varies with flux density, current and length of a wire using a top pan balance. ATa. Use appropriate analogue apparatus to record a range of measurements (to include length/distance). ATb. Use appropriate digital instruments to obtain a range of measurements (to include current, mass). ATf. correctly construct circuits from circuit diagrams using DC power supplies, cells, and a range of components Knowledge Capacitors: Capacitance, energy stored in a capacitor, charging and discharging a capacitor and dielectrics Magnetic fields: Current-carrying conductors in a magnetic field, moving charges in a magnetic field, charged particles in circular orbits Electromagnetic induction: Generating electricity, the laws of electromagnetic induction, the alternating current generator and transformers. Rationale Content in this section will deepen the understanding of the forces that a magnetic field exerts on current carrying conductors and moving charges. Again this reinforces the concept of a force acting at a distance and links it to electrical fields as well. This provides a mathematical understanding of in terms of a field surrounding and object and the variation of the acting force due to its mass or charge or due to an electric current passing through it. This then provides further understanding of the use of the theory in everyday applications such as alternating current generators and transformers used to provide electricity for use.

## knowledge Organiser

A knowledge organiser is an important document that lists the important facts that learners should know by the end of a unit of work. It is important that learners can recall these facts easily, so that when they are answering challenging questions in their assessments and GCSE and A-Level exams, they are not wasting precious time in exams focusing on remembering simple facts, but making complex arguments, and calculations.

We encourage all pupils to use them by doing the following:

• Quiz themselves at home, using the read, write, cover, check method.
• Practise spelling key vocabulary
• Further researching people, events and processes most relevant to the unit.
