Trying out adding arrows
Physics Narrative
for 11-14
Adding force arrows to a familiar situation

The image shows a situation familiar to most teachers. Think how this will look when seen through forces spectacles. Focus on the forces which act on the hanging masses.
Make a simplifying sketch to model
the forces acting on the hanging masses.
Here's what to do:
- Identify one object.
- Isolate that object from it's environment.
- Identify the forces acting by thinking about interactions with the environment.
In episodes 2 and 3 we'll introduce a kind of force-spotter's guide – a series of clues to look for in the environment that allow you to identify the force arrows to add to your description.
Teacher Tip: Don't forget to actually try to do the drawing.
