Physics Year 11 - Module 2 - Lesson 5
Acceleration and Graphical Analysis
1. Key Ideas
A graph is not just a picture of data — it is a proof. The gradient of a force vs acceleration graph is a measurement of mass, and from that single line Newton's Second Law emerges.
- What a v-t graph gradient and area represent
- Why gradient of F vs a graph = mass
2. Success Criteria
By the end, you should be able to:
- What a v-t graph gradient and area represent
- What an F vs a graph gradient represents
- F net = ma as derived from graphical data

5. Short Answer Questions
1. Explain this lesson goal in your own words: "What a v-t graph gradient and area represent". Use one specific example from the lesson.
2. Apply this idea to a new example: "What an F vs a graph gradient represents". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Acceleration and Graphical Analysis: "F net = ma as derived from graphical data".
6. Extend: Apply the Idea
A student gives a memorised answer about Acceleration and Graphical Analysis but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
