2. Kinetic energy and gravitational potential energy

Available for over a year

In this episode, Ellie Hurer and James Stewart explore kinetic energy, gravitational potential energy, and elastic potential energy. They then share the key equations you need to calculate them. Suitable for: AQA, Edexcel, OCR. For more information on kinetic energy and gravitational potential energy, check out the BBC Bitesize website: https://www.bbc.co.uk/bitesize/guides/z8hsrwx/revision/5 Key learning objectives discussed in this episode: - Students should be able to calculate the amount of energy associated with a moving object, a stretched spring and an object raised above ground level. The kinetic energy of a moving object can be calculated using the equation: kinetic energy = 0.5 × mass × speed 2 - The amount of elastic potential energy stored in a stretched spring can be calculated using the equation: elastic potential energy = 0.5 × s prang constant × extension 2 (assuming the limit of proportionality has not been exceeded) - The amount of gravitational potential energy gained by an object raised above ground level can be calculated using the equation: g. p. e. = mass × gravitational field strength × height
