I know that friction is a force
I can give one or two examples of how friction can be increased.
I can group surfaces into ‘high friction’ and ‘low friction’
I can identify which shapes move easily through water and explain this in terms of reduction of resistance
I use a forcemeter to measure forces, reading the scale accurately
I can think of an everyday situation eg holding the handlebars on a bicycle or pulling a drawer out of a desk and decide whether it is important for friction to be high or low
