NSSCAS Physics (8225) · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Mechanics and kinematics & Forces, momentum and Newtonian mechanics

  • Derive and apply the four kinematic equations for uniform acceleration to solve multi-stage motion problems (projectiles, free fall, two-part journeys) without referring to notes

  • Resolve vectors into perpendicular components and reconstruct resultants, including relative velocity problems involving river crossings and wind

  • Analyse motion on inclines and in lifts, distinguishing apparent weight from true weight

  • Interpret displacement-time, velocity-time and acceleration-time graphs, converting between them by gradient and area

Your checkpoint

Week 2

Mechanics and kinematics & Forces, momentum and Newtonian mechanics

  • Apply conservation of momentum to collisions and explosions in one and two dimensions, classifying elastic versus inelastic cases
