Assessment homes come from the parsed Pearson specification (content summaries & assessment overviews). Hover a chip for the printed rule. Filters appear only where the qualification has that structure — a linear IGCSE has no unit scope, and only Maths A splits Foundation / Higher tiers.

1. Kinematics of a particle moving in a straight line or plane

1.1Motion in a vertical plane with constant acceleration, e.g. under gravity.M2
1.2Simple cases of motion of a projectile.M2
1.3
Velocity and acceleration when the displacement is a function of time.:
- The setting up and solution of equations of the form dx = f(t) or dv = g(t) will be consistent with the level of dt dt calculus in P1, P2 P3 and P4.

1.4
Differentiation and integration of a vector with respect to time. Centres of mass:
- For example, given that r = t³⁄2 i + t² j, find ṙ and r̈ at a given time.

2. Centres of mass

1. Centres of mass

2.1Centre of mass of a discrete mass distribution in one and two dimensions.M2
2.2Centre of mass of uniform plane figures, and simple cases of composite plane figures. The use of an axis of symmetry will be acceptable where appropriate. Use of integration is not required. Figures may include the shapes referred to in the formulae book. Results given in the formulae book may be quoted without proof.M2
2.3
Simple cases of equilibrium of a plane lamina. k and energy:
- The lamina may (i) be suspended from a fixed point;(ii) be free to rotate about a fixed horizontal axis;(iii) be put on an inclined plane.

3. Work and energy

1. Work and energy

3.1Kinetic and potential energy, work and power. The work-energy principle. The principle of conservation of mechanical energy. Problems involving motion under a constant resistance and/or up and down an inclined plane may be set.M2

4. Collisions

1. Collisions

4.1Momentum as a vector. The impulse-momentum principle in vector form. Conservation of linear momentum.M2
4.2Direct impact of elastic particles. Students will be expected to know and use the inequalities Newton’s law of restitution. Loss of 0 ≤ e ≤ 1 (where e is the coefficient of restitution). mechanical energy due to impact.M2
4.3Successive impacts of up to three particles or two particles and a smooth plane surface. Collision with a plane surface will not involve oblique impact.M2

5. Statics of rigid bodies

1. Statics of rigid bodies

5.1Moment of a force.M2
5.2Equilibrium of rigid bodies. Problems involving parallel and non-parallel coplanar forces. Problems may include rods or ladders resting against smooth or rough vertical walls and on smooth or rough ground.M2
