Agree Learning Outcomes: Topic: P7.1.3 Energy analysis with forces 2 Spec link: P7.1b, c,d and e Time: 70 mins Recorded Assessment: Review: Students check their analyses. Present New Knowledge: Think about what happened to KE when a driver applies their brakes and decelerates. Agree Learning Outcomes: Describe the energy changes involved when work is done on objects e.g. acceleration and lifting. Calculate the changes in different types of energy. Apply To Demonstrate: Student construct energy analysis diagrams of new situation and complete calculations. Construct Meaning: Draw an energy analysis for several different situations and compare them. Introduce electrical energy analysis.

Tell me as much as you can about this picture… Bell Tell me as much as you can about this picture…

What we learnt last time... Write a paragraph in your book explaining what is happening in the energy analysis below. What is the physical situation?

LO Learning outcomes Describe the energy changes involved when work is done on objects e.g. acceleration and lifting. Calculate the changes in different types of energy.

What happens when we apply the brakes to a car? NK What happens when we apply the brakes to a car? Think about this situation and write a description for the physical situation under ‘Point 1’, ‘Transfer’ and ‘Point 2’.

What happens when we apply the brakes to a car? NK What happens when we apply the brakes to a car? Great! Now draw an energy analysis for ‘Point 1’ and ‘Point 2’ below? Add a brief description of the ‘Transfer’.
