# Topic 1 Year 9 physics

 Physics Topic Energy 2 No of lessons 10 When is it happening Year 9 Term 2 What will students learn The term work and examples where work is done, including displacements and deformations. How levers, pulleys and wheels are all used to make work easier. Use the formula: work done (J) = force (N) x distance moved (m) to compare energy transferred for objects moving horizontally. Why thermal energy transfer occurs, examples and relate this to changes in temperature. The thermal insulation of different materials. The three ways energy can be moved from one place to another by heating. Key Knowledge that students should know at the end of 'Topic' This is the knowledge that students will meet for the first time in this topic The term work and give examples where work is done, including displacements and deformations. Examples of how levers, pulleys and wheels are all used to make work easier. The formula: work done (J) = force (N) x distance moved (m) to compare energy transferred for objects moving horizontally. Why thermal energy transfer occurs, give examples and relate this to changes in temperature. The three ways energy can be moved from one place to another by heating. This is knowledge that students may have met before but will need to deepen their understanding From KS2- The effect of simple mechanisms such as levers, pulleys and gears.           From forces 1- How unbalanced forces cause motion of an object.                                                              From energy 1- How energy can transfer between one store and another, dissipation and conservation of energy.                     From matter 1- the particle model of matter. Key Skills that students should be able to demonstrate at the end of 'Topic' This is the skills  that students will meet for the first time in this topic Use the formula: work done (J) = force (N) x distance moved (m) to compare energy transferred for objects moving horizontally. Carry out an investigation into the thermal insulation of different materials. Sketch a graph to show the pattern of temperature change against time.  Evaluate claims about insulation in the home or for clothing technology. This is skills that students may have met before but will need to develop Students will have some experience of graph drawing from ks2 and year 7 from various topics. Key vocabulary that students should know and understand work, deformation, displacement, input/output force, thermal conductor, thermal insulator, temperature, conduction, convection, radiation, thermochromic film. The Big Question What is work and how can heat energy be transferred? Key questions that students should be able to answer at the end of the 'Topic' What does the term 'work' mean and what effect can it have on objects How do levers, pulleys and gears make work easier? How can 'work' be calculated? Why does thermal energy transfer occur? What is the difference between energy and temperature? Explain how thermal energy is transferred by conduction. Explain how thermal energy is transferred by convection Explain how thermal energy is transferred by radiation.
