Teaching Guidance for 11-14 Supporting Physics Teaching

Preliminary ideas

Before looking at the relationship between forces and speed it is important for pupils to understand clearly that:

  • Several forces can act on an object at the same time.
  • Equal forces acting in opposite directions add to zero.
  • Stationary objects (at rest) have a resultant force equal to zero.

These ideas were covered in the SPT: Forces topic.
