Explain that a non-zero resultant force can change an object's motion.

In the subtopic Resultant forces, this learning objective focuses on explain that a non-zero resultant force can change an object's motion. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Resultant forces and Forces and their interactions. Approved keywords for this objective include 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 explain that a non-zero resultant force can change an object's motion. This is not a generic revision point: it is specifically about Resultant forces, Forces and their interactions, and the approved wording of the learning objective.
