Secondary 3 Physics – LearnSphere

About Course

This course is designed for Secondary 3 students pursuing Physics under the Singapore-Cambridge O-Level (6091) syllabus. It lays a strong foundation in key physics principles and problem-solving skills through structured lessons, real-world applications, and visual demonstrations.

Topics include measurement techniques, kinematics, dynamics, energy, pressure, and turning effects — all supported with concise video explanations, guided worksheets, and interactive quizzes.

Students will build a solid conceptual understanding while developing analytical thinking and mathematical skills essential for success in upper secondary Physics and national exams.

Master key Physics concepts aligned with the O-Level syllabus
Understand kinematics, dynamics, and forces in real-world contexts
Analyse motion using displacement-time and velocity-time graphs
Solve problems using formulas involving work, energy, and power
Gain confidence in applying concepts like pressure, thermal energy, and moments
Build strong graphing and data interpretation skills
Develop practical thinking for experimental setups and analysis

Course Content

Physical Quantities, Units and Measurement
This topic introduces students to the fundamental building blocks of physical science — quantities, units, and the tools of measurement.

Kinematics
Understand motion in one dimension through definitions, calculations, and graphical interpretations.

Dynamics
Study the forces that cause changes in motion, including Newton’s Laws and frictional effects.

Turning Effect of Forces
Understand how forces cause rotational motion and how equilibrium is maintained.

Pressure
Introduce the concept of pressure in solids and fluids, including atmospheric pressure.

Energy
Dive into energy transformations, calculations, and how energy is stored or transferred.

Thermal Properties of Matter
This topic introduces how thermal energy affects matter in terms of temperature, state, and internal energy.

Transfer of Thermal Energy
This topic focuses on the three modes of thermal energy transfer: conduction, convection, and radiation.

Kinetic Model of Matter
Explore how matter behaves at the microscopic level and how this explains macroscopic phenomena.
