3. Work done and energy transfer

Available for over a year

This podcast series is all about forces. In this episode James Stewart and Ellie Hurer explore work done, energy transfer and how friction transfers kinetic energy into thermal energy. They also share the key equation needed to calculate work done and discuss how to describe energy transfers. Suitable for: AQA, Edexcel, OCR. For more information on work done and energy transfer, check out the BBC Bitesize website: https://www.bbc.co.uk/bitesize/guides/zgncjty/revision/3 Key learning objectives discussed in this episode: - When a force causes an object to move through a distance work is done on the object. So, a force does work on an object when the force causes a displacement of the object. - The work done by a force on an object can be calculated using the equation: work done = force × distance - One joule of work is done when a force of one Newton causes a displacement of one metre. - 1 joule = 1 newton-metre - Students should be able to describe the energy transfer involved when work is done. - Students should be able to convert between Newton Metres and joules. - Work done against the frictional forces acting on an object causes a rise in the temperature of the object.
