Explain that a non-zero resultant force causes acceleration.

In the subtopic Newton's laws of motion, this learning objective focuses on explain that a non-zero resultant force causes acceleration. 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 resultant force and acceleration. A strong answer separates velocity and acceleration, uses correct units where quantities are involved, and links the physical reasoning back to explain that a non-zero resultant force causes acceleration. 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.
