AQA Physics Equation Sheet

Answer: If you are studying AQA Physics, having a comprehensive physics equation sheet is vital to effectively prepare for your exams. The AQA Physics syllabus covers a broad range of topics, each necessitating a deep understanding of various equations. Below, we will discuss key equations that you need to be familiar with for both AQA GCSE and AQA A-Level Physics.

1. AQA GCSE Physics Equations

Energy:

  • Kinetic Energy: E_k = \frac{1}{2}mv^2
  • Gravitational Potential Energy: E_p = mgh
  • Efficiency: \text{Efficiency} = \frac{\text{Useful Energy Output}}{\text{Total Energy Input}} \times 100

Electricity:

  • Ohm’s Law: (V = IR)
  • Electrical Power:
    • P = VI
    • P = I^2R
    • P = \frac{V^2}{R}

Waves:

  • Wave Speed: v = f \lambda

Forces:

  • Newton’s Second Law: (F = ma)
  • Weight: (W = mg)
  • Hooke’s Law: (F = kx)
  • Moments:
    • M = Fd
    • \text{Moment} = \text{Force} \times \text{Perpendicular distance from Pivot}

General:

  • Density: \rho = \frac{m}{V} (Density = mass/volume)
  • Pressure:
    • P = \frac{F}{A}
    • P = \frac{h \rho g}{A}

2. AQA A-Level Physics Equations

Mechanics:

  • Kinematic Equations:
    • v = u + at
    • s = ut + \frac{1}{2}at^2
    • v^2 = u^2 + 2as

Circular Motion:

  • Centripetal Force: F_c = \frac{mv^2}{r}
  • Centripetal Acceleration: a_c = \frac{v^2}{r}

Momentum:

  • Linear Momentum: (p = mv)
  • Impulse: (J = Ft)
  • Conservation of Momentum:
    • m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2

Thermodynamics:

  • Ideal Gas Law: PV = nRT
  • First Law of Thermodynamics: \Delta U = Q - W

Oscillations and Waves:

  • Simple Harmonic Motion (SHM):
    • a = -\omega^2 x
    • x = A\cos(\omega t)
    • \omega = 2\pi f

Electricity and Magnetism:

  • Capacitance: C = \frac{Q}{V}
  • Coulomb’s Law: F = k \frac{q_1 q_2}{r^2}
  • Magnetic Flux: \Phi = B A \cos(\theta)
  • Faraday’s Law: \mathcal{E} = -\frac{d \Phi}{d t}

3. Preparing for Exams:

  • Memorization Tips:

    • Make use of mnemonic devices to memorize equations.
    • Practice problems that use these equations to understand their applications.
    • Create flashcards with equations on one side and their applications on the other.

  • Understanding the Concepts:

    • It’s crucial to not just memorize the equations but understand the underlying physics concepts.
    • Utilize textbooks, online resources, and past papers to get a firm grasp on how these equations are applied to real-world problems.

By having a solid understanding of these equations and regularly practicing their applications in various scenarios, you’ll be well-prepared to excel in your AQA Physics exams. Make sure to review your teacher’s provided equation sheets and any official materials from the AQA syllabus for the most accurate and updated information.
