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.
Don't forget to actually try to do the drawing.
