Mastery checklist

Know what success looks like.

  1. 01

    Define the system, then show every external interaction with a clear direction.

  2. 02

    Apply Newton's laws or a conservation law component by component.

  3. 03

    Test the result against units, limiting cases, and the direction of the predicted change.

Exam lens

Build, apply, check.

3 Dynamics sits inside AS Level foundations. Build the concept first, then practise selecting a model, showing working, and checking the final result.
