All of AQA PHYSICS Paper 1 in 40 minutes - GCSE Science Revision

Introduction

This tutorial provides a comprehensive overview of key concepts covered in the AQA Physics Paper 1, suitable for GCSE Science revision. It breaks down essential topics, making it easier to grasp the material in a structured manner. Whether you're preparing for an exam or seeking to reinforce your understanding, this guide will help you review core physics principles effectively.

Step 1: Understanding Energy Stores

• Familiarize yourself with different types of energy stores:

  • Kinetic Energy: Energy of moving objects.
  • Gravitational Potential Energy (GPE): Energy possessed by an object due to its height.

• Learn the formulas:

  • Kinetic Energy: [ KE = \frac{1}{2} mv^2 ]
  • GPE: [ GPE = mgh ]
  • where ( m ) is mass, ( v ) is velocity, ( g ) is acceleration due to gravity, and ( h ) is height.

Step 2: Energy Transfers

• Understand how energy is transferred between stores:

  • Energy can be transferred through work done (mechanical), heating, and radiation.

• Explore examples of energy transfers in different scenarios, such as a falling object converting GPE to KE.

Step 3: Specific Heat Capacity Practical

• Review the concept of specific heat capacity, which is the amount of energy needed to raise the temperature of 1 kg of a substance by 1°C.
• Conduct a practical experiment to measure the specific heat capacity of a material:
  • Use a calorimeter.
  • Measure the initial temperature, apply heat, then measure the final temperature.
  • Calculate specific heat capacity using: [ c = \frac{Q}{m\Delta T} ]
  • where ( Q ) is heat energy, ( m ) is mass, and ( \Delta T ) is the change in temperature.

Step 4: Power and Efficiency

• Understand the definitions:

  • Power: The rate at which energy is transferred or converted.
  • Efficiency: The ratio of useful energy output to total energy input.

• Use the formulas:

  • Power: [ P = \frac{E}{t} ]
  • Efficiency: [ \text{Efficiency} = \frac{\text{Useful Energy Output}}{\text{Total Energy Input}} \times 100% ]

Step 5: Energy Sources

• Identify renewable and non-renewable energy sources:

  • Renewable: Solar, wind, hydro, geothermal.
  • Non-renewable: Fossil fuels, nuclear.

• Discuss the advantages and disadvantages of each type.

Step 6: Circuit Basics in Electricity

• Understand basic circuit components:

  • Current: Flow of electric charge.
  • Voltage: Potential difference that drives current.

• Learn how to draw simple circuit diagrams.

Step 7: Ohm's Law and Resistance

• Apply Ohm's Law: [ V = IR ]
• Understand resistance and how it impacts current flow in a circuit.

Step 8: Series and Parallel Circuits

• Compare series and parallel circuits:
  • Series: Current is the same, total resistance is the sum of individual resistances.
  • Parallel: Voltage is the same, total resistance is less than the smallest resistance.

Step 9: Thermistors and LDRs

• Learn about temperature-sensitive resistors (thermistors) and light-dependent resistors (LDRs):
  • Thermistors decrease resistance with increasing temperature.
  • LDRs decrease resistance with increasing light intensity.

Step 10: Electrical Power and Safety

• Understand electrical power calculations: [ P = IV ]
• Discuss the significance of alternating current (A.C.) vs. direct current (D.C.) and safety precautions when dealing with mains electricity.

Step 11: The National Grid and Transformers

• Learn how the National Grid distributes electricity efficiently and the role of transformers in voltage change.

Step 12: Static Electricity and Electric Fields

• Explore the principles of static electricity and how electric fields operate.

Step 13: Density and States of Matter

• Understand density: [ \text{Density} = \frac{mass}{volume} ]
• Review the three states of matter: solid, liquid, gas, and their properties.

Step 14: Internal Energy and Heating Curves

• Explore internal energy and how it changes with temperature and phase transitions.

Step 15: Gases and Their Behavior

• Review gas laws and key concepts like pressure, volume, and temperature relationships.

Step 16: Nuclear Physics Basics

• Understand atomic structure, including protons, neutrons, and electrons.
• Learn about nuclear decay equations and types of radiation: alpha, beta, and gamma.

Step 17: Radioactivity and Half-Life

• Understand the concept of half-life in radioactive decay and how it affects stability.

Step 18: Fission and Fusion

• Discuss differences between nuclear fission (splitting of atoms) and fusion (combining of atoms).
