Forces - box diagrams (free body diagrams) Physics

A presentation and worksheet introducing and explaining box diagrams (or free body diagrams). This is part of a module on forces.
The presentation introduces it and has several examples for you to talk through and then some for the boys to try verbally or in pairs.
There is then a worksheet I have made. 4 diagrams to do and then 4 spaces for the students to try writing their own - and for partners to have a go at. Little bit of metacognition…tick!
