Edexcel IGCSE Physics topic guide
Edexcel IGCSE Physics Forces and motion questions
Forces and motion connects descriptions of movement with the forces that change speed, direction and shape. It also covers momentum, moments and the mechanics of everyday situations.
Forces and motion topic overview
Forces and motion connects descriptions of movement with the forces that change speed, direction and shape. It also covers momentum, moments and the mechanics of everyday situations.
Translate each situation into a diagram or graph, choose the relationship that matches the quantities given, and keep vector directions and units explicit.
Question types in forces and motion
- Distance-time and velocity-time graph interpretation, including gradients and areas.
- Calculations involving speed, acceleration, force, weight, momentum and moments.
- Explanations of stopping distance, terminal velocity, deformation and safety features.
- Practical questions on motion, force-extension behaviour and measuring physical quantities.
Forces and motion subtopics
