Identify friction, air resistance, tension and normal contact force as contact forces.

In the subtopic Contact and non-contact forces, this learning objective focuses on identify friction, air resistance, tension and normal contact force as contact forces. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Contact and non-contact forces and Forces and their interactions. Approved keywords for this objective include force, contact force, friction, air resistance, tension, and normal contact force. A strong answer separates scalar and vector quantities, uses correct units where quantities are involved, and links the physical reasoning back to identify friction, air resistance, tension and normal contact force as contact forces. This is not a generic revision point: it is specifically about Contact and non-contact forces, Forces and their interactions, and the approved wording of the learning objective.
