Simon's car has run out of fuel. He must push his car 5 metres to the petrol pump, using a force of 200N. How much work does Simon do?
This question asks students to recall the equation Work done = Force x Distance.
In this question, students must multiply 200 by 5, with the answer being 1000 Joules.
It is important that the students remember the unit of work done.
This question can be developed by asking students to rearrange the question, asking: If Simon uses the same force and pushes the car for 38 metres, what is Simon's total work done, including the first 5 metres?
