AS Level Physics - 5.1 Energy Conservation

**This Powerpoint specifically uses the Cambridge AS Level international Syllabus (9702) and covers all criteria for – Unit 5.1 Energy Conservation
**

Students will be able to -

1 understand the concept of work, and recall and use work done = force × displacement in the direction of the force

2 recall and apply the principle of conservation of energy

3 recall and understand that the efficiency of a system is the ratio of useful energy output from the system to the total energy input

4 use the concept of efficiency to solve problems

5 define power as work done per unit time

6 solve problems using P = W/t

7 derive P = Fv and use it to solve problems

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
