UNIT OVERVIEW

This revision unit brings together everything you have learned in Grade 10 Physical Sciences. You will revisit key concepts, practise problem-solving, and prepare for your examinations.

By the end of this unit, you will be able to:

• Apply conservation of mechanical energy to solve motion problems
• Analyse transverse and longitudinal wave properties
• Calculate photon energies and understand the electromagnetic spectrum
• Balance chemical equations and perform stoichiometric calculations
• Explain atomic structure and periodic table trends
• Solve electric circuit problems using Ohm's law
• Interpret graphs of motion and wave phenomena

Key applications:

• Roller coaster physics — energy conservation in theme park rides
• Medical ultrasound — longitudinal sound waves for imaging
• Solar panels — electromagnetic radiation and photon energy
• Water purification — precipitation reactions and ion testing
• Lightning protection — electrostatic principles
• Bungee jumping — energy transformation between gravitational potential and kinetic energy
