The Forces and motion module gathers the motion and forces content of Physics 2 in WJEC GCSE Science Double Award. It explains how to describe motion, how forces change motion, and the energy involved. This page maps the module and links to a focused answer page for each part.
The topics in this module
- Distance, speed and acceleration
- Speed and acceleration and reading motion graphs. See Distance, speed and acceleration.
- Newton's laws and forces
- Balanced and unbalanced forces, Newton's laws and F = ma. See Newton's laws and forces.
- Work, energy and power
- Work, power, kinetic and potential energy and conservation of energy. See Work, energy and power.
- Stopping distances and safety
- Thinking, braking and stopping distances and safety features. See Stopping distances and safety.
How this module fits the exam
These topics sit in Unit 6 (Physics 2), a written paper of 1 hour 15 minutes worth 15%. Questions mix calculation (the equations), graph interpretation, and explanation (forces, stopping distances).
How to study this module
- Master the equations. Speed, acceleration, F = ma, work, power and the energy equations.
- Read motion graphs. Gradient and area on distance-time and velocity-time graphs.
- Understand forces. Balanced and unbalanced, weight versus mass, and terminal velocity.
- Know energy. The stores, conservation, and work against friction becoming heat.
- Learn stopping distances. The factors and how safety features reduce the force.
Then test yourself with the module quiz.
