Physics — A Level

British Curriculum · Cambridge Assessment International Education · Years 12-13 · Ages 16-18

Cambridge International AS & A Level Physics (9702) is a prerequisite for engineering and physical science degrees, and is assessed by theory papers plus a laboratory practical examination that carries significant weight.

AS covers physical quantities and units, kinematics, dynamics, forces, work energy and power, deformation of solids, waves, superposition, electricity, DC circuits and particle physics. A2 adds circular motion, gravitational fields, temperature, ideal gases, thermodynamics, oscillations, electric and magnetic fields, capacitance, alternating currents, quantum physics, nuclear physics and medical imaging.

The practical papers examine experimental design, uncertainty propagation and graphical analysis. Uncertainties in particular are a reliable source of lost marks and are rarely taught to the depth the exam demands.

Key topics covered

• Kinematics & DynamicsMotion, Newton's laws, momentum, work, energy, power and materials.
• Waves & SuperpositionWave properties, interference, diffraction, stationary waves and the Doppler effect.
