1. Key Ideas

A car on a hill. Six formulae. One coherent picture. This lesson connects every energy concept from Phase 2 into a single chain — and shows how each calculation feeds the next.

All six Phase 2 formulae and their conditions
Why each calculation in a chain feeds the next

2. Success Criteria

By the end, you should be able to:

All six Phase 2 formulae and their conditions
Three energy categories: stored, transferred, lost
How each formula connects to adjacent formulae

3. Key Terms

frictionpresent and mechanical energy is not conserved

accounting for energythe foundation of every dynamics problem

Energynever created or destroyed — only converted

your final KEless than the initial PE, the difference went somewhere

The formulaenot separate tools — they are different views of the same energy accounting system

5. Short Answer Questions

1. Explain this lesson goal in your own words: "All six Phase 2 formulae and their conditions". Use one specific example from the lesson.

Band 32 marks

2. Apply this idea to a new example: "Three energy categories: stored, transferred, lost". Show your reasoning clearly.

Band 43 marks

3. Analyse why this idea matters for understanding Energy Synthesis: "How each formula connects to adjacent formulae".

Band 54 marks

6. Extend: Apply the Idea

Band 5/65 marks

A student gives a memorised answer about Energy Synthesis 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.

7. Multiple Choice

1. What is the best first step when answering a question about Energy Synthesis?

A. Identify the key concept being tested

B. Write every fact from memory

C. Ignore the command word

D. Skip examples and evidence

2. Which answer would show stronger understanding of Energy Synthesis?

A. An answer with accurate terms and reasoning

B. A copied definition only

C. A single-word response

D. An answer with no example

3. What should you do if a question asks you to explain?

A. Link the idea to a reason or cause

B. List unrelated facts

C. Only draw a diagram

D. Write the shortest possible answer

8. Success Criteria Proof

Finish with evidence that you can do each success criterion.

Success criterion 1

Prove that you can: All six Phase 2 formulae and their conditions
