Year 12
Side A3: Forces, Density, Pressure and Dynamics
Develop mechanics through moments, density, pressure, upthrust, friction, momentum, Newton's laws, impulse, and 2D collisions.
Part of Year 12 CIE Physics 9702.
Topic Overview
What students will cover
This topic gathers the main AS dynamics ideas into one sequence. Students should see forces, fluids, momentum, and collisions as connected models rather than isolated equations.
