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.
