Quick explanation
R5 Understand and use addition of forces, resultant forces and dynamics for motion in a plane
- This point belongs to Mechanics, especially Resultant forces and dynamics.
- You need to be able to r5 Understand and use addition of forces, resultant forces and dynamics for motion in a plane.
- The key ideas to know are dynamics, motion in a plane, and resultant forces.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
