New GCSE AQA Physics lesson on 'Work done' written in line with new AQA Physics specification.
Starter - Students are to discuss what objects they think would be the most 'work' to move into a house. This is to get them thinking about what work means - more work or less work.
The familiar definition of work is explored which is then related to the definition of work in physics. A quick mini plenary questions students on different scenarios to see if work is done on the system or not.
After the equations for Work done is given and explained students re-visit the moving house activity to calculate the work done on moving different objects into a house.
An experiment is detailed to explore work done on different surfaces to start investigating the effects of friction in relation to work done. The lesson concludes looking at useful friction and the changes in energy stores cause by friction.
Exam questions are given as a plenary task.
Lesson Objectives:
1) Provide a definitions for work done.
2) Recall and apply the equation for Work done to solve problems.
3) Calculate the energy changes in different systems using work done.
4) Detail the energy changes that occur in a system when work is done.

This was great thanks
Slide 10 the arrow needs extending and the first question on last slide needs the 30 000J work done value. Also work done = KE lost may be a jump too far at this stage in the course (my learners have just begun)<br /> Other than that it's brilliant and saved my bacon as I've had a lot to plan this weekend.<br /> Very grateful, Aggie
