  • Environmental impact
• Energy Transfer and Transformation
  • Conservation of energy
  • Different forms of energy (e.g., kinetic, potential)

Electromagnetism

• Magnetism: The force exerted by magnets
  • Key Points: Magnetic fields, properties of magnets
• Electric and Magnetic Fields: Regions around a charge/magnet where influence is felt
  • Key Points: Interaction between electric/magnetic fields

  • Key Points: Causes (e.g., friction), discharge (e.g., lightning)
• Electromagnetic Forces: Forces associated with electric and magnetic fields

Induction, AC and DC

• Induction: Process by which a conductor moving through a magnetic field induces a current
• AC (Alternating Current): Current direction changes periodically
• DC (Direct Current): Current flows in one direction only
• Current: The flow of electric charge
• Voltage: The electric potential difference between two points
• Power: Rate at which electrical energy is transferred

Generation and Transmission of Electricity

• Key Points: Power stations, transmission lines

Electric Circuits

• Definition: A closed loop allowing current to flow from a voltage source
• Components: Resistors, capacitors, inductors, etc.

Astrophysics

• The Solar System: Collection of the sun and celestial bodies bound by gravity
  • Key Points: Planets, moons, asteroids, comets
• Planets and Satellites: Planets are large celestial bodies orbiting a star; satellites orbit planets
  • Key Points: Planet orbits, satellite orbits

The Big Bang Theory

• Definition: Leading explanation for the universe's beginning
• Key Points: Evidence (e.g., cosmic microwave background radiation, redshift of galaxies)

Heat, Light, and Sound

• Thermal Physics: Study of heat, temperature, and their relationship to energy and work
