Trying out adding arrows(Self check)



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.
