1. Key Ideas

Every force you have ever felt had a source — and that source felt something back.

What a force is and its SI unit
Why forces always act in pairs on different objects

2. Success Criteria

By the end, you should be able to:

What a force is and its SI unit
The difference between contact and field-mediated forces
Newton's First Law — qualitative statement

3. Key Terms

5. Short Answer Questions

1. Explain this lesson goal in your own words: "What a force is and its SI unit". Use one specific example from the lesson.

Band 32 marks

2. Apply this idea to a new example: "The difference between contact and field-mediated forces". Show your reasoning clearly.

Band 43 marks

3. Analyse why this idea matters for understanding Forces and Interactions: "Newton's First Law — qualitative statement".

Band 54 marks

6. Extend: Apply the Idea

Band 5/65 marks

A student gives a memorised answer about Forces and Interactions 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.

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 Forces and Interactions?

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
