• Equations of Motion

  • Uniform motion

  • Equations for uniformly accelerated motion

• Free Fall

  • Effects of gravity

  • Terminal velocity

• Practical Applications

  • Analyzing real-world motion (e.g., vehicles, projectiles)

Module 2: Forces and Newton's Laws

• Fundamental Forces

  • Gravitational, electromagnetic, strong nuclear, and weak nuclear forces

• Newton's Laws of Motion

  • First Law: Inertia

  • Second Law: F = ma

  • Kinetic energy (KE = 1/2 mv²)

  • Potential energy (PE = mgh)

• Conservation of Energy

  • Law of conservation of energy

  • Energy transformations (e.g., mechanical, thermal)

• Power

  • Definition and calculation (P = W/t)

  • Units of power (Watts)

• Practical Applications

  • Energy efficiency and renewable energy sources

Module 4: Waves and Sound

• Wave Properties

  • Types of waves: transverse and longitudinal

  • Characteristics: wavelength, frequency, amplitude, speed

• Sound Waves

  • Production and propagation of sound

  • Speed of sound in different media

• Wave Behavior

  • Reflection, refraction, diffraction, and interference

• Applications of Waves

  • Doppler effect and its implications

  • Uses of sound in technology (e.g., ultrasound, sonar)

This outline provides a structured overview of the key topics and concepts covered in Year 11 Physics across the first four modules.
