Some good bits - but also mistakes/simplifications. The first example gives the weight of a box, and then the the distance travelled is horizontal. You can't use the weight to calculate the work done in that direction, only the amount lifted. Work done is Force x distance travelled along the line of action of the force. There is no mention of that in this resource. Worksheet is ok for a low set class - for a high set you'll want to make some examples that include things being lifted up a slope for example, so that students have to work out which distance to use in the equation.
Exactly what I needed, thanks!
I used the practice Q's on the board to get pupils to answer on mwb's in pairs, then got them to answer q's from the worksheet, then they peer assessed (thanks for including answers!) Very interactive lesson, didn't require any planning!
