Identify sources of uncertainty in an acceleration practical.

In the subtopic Required practical: acceleration, this learning objective focuses on identify sources of uncertainty in an acceleration practical. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Required practical: acceleration and Forces and motion. Approved keywords for this objective include acceleration and uncertainty. A strong answer separates velocity and acceleration, uses correct units where quantities are involved, and links the physical reasoning back to identify sources of uncertainty in an acceleration practical. This is not a generic revision point: it is specifically about Required practical: acceleration, Forces and motion, and the approved wording of the learning objective.
