  • ✓identify and explain the difference between vectors and scalars
  • ✓add vectors such as forces and velocities using scale drawings and the parallelogram law
  • ✓add vectors which are parallel, anti-parallel or at right angles by calculation
  • ✓explain how friction is caused and how it can be reduced
  • ✓state the relationship between mass and weight

Two boats travelling at the same speed can end up in very different places if they travel in different directions. In Physics, this is why vectors are needed. In this lesson, we learn how to combine forces and velocities to predict what really happens. Mnemonic for vectors: MAD (Magnitude. Arrow. Direction).
