State Newton's first law in terms of motion remaining unchanged when resultant force is zero.

In the subtopic Newton's laws of motion, this learning objective focuses on state Newton's first law in terms of motion remaining unchanged when resultant force is zero. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Newton's laws of motion and Forces and motion. Approved keywords for this objective include Newton's first law and resultant force. A strong answer separates resultant force and balanced forces, uses correct units where quantities are involved, and links the physical reasoning back to state Newton's first law in terms of motion remaining unchanged when resultant force is zero. This is not a generic revision point: it is specifically about Newton's laws of motion, Forces and motion, and the approved wording of the learning objective.
