Motion and Forces
A reviewed 8867 repair guide for Motion and Forces.
Before you begin
Use the diagnostic first. Complete the assigned explanation, worked transfer, guided practice and independent practice in order before the assessment and delayed re-test.
How the ideas connect
- Kinematics, graphs and uniform acceleration
- Mass, inertia and linear momentum
- Newton’s laws and resultant force
Learn in order
Lesson route
Objective clusters
- 01Kinematics, graphs and uniform accelerationUse gradient and signed area according to the plotted quantities, and apply constant-acceleration equations only when acceleration is uniform.
- 02Mass, inertia and linear momentumMass measures inertia; linear momentum is the vector product of mass and velocity.
- 03Newton’s laws and resultant forceThird-law forces act on different bodies; use the resultant force on the chosen body and F = ma only for constant mass.

Course coverage and review details
Restricted to 8867 topic 3(a)–(i), PDF page 12; H2-only depth and omitted H2 topics do not contribute to this profile.
Recorded selected-response work supports formative repair. It does not by itself prove constructed, diagrammatic or practical performance.
