1. SciDoc Gravitational potential energy Gravitational potential energy 1. What type of objects store kinetic energy? 2. A moving van has a kinetic energy of 800,000 and a velocity of 20 m/s. What is the mass of the van? Last Lesson Last Term Last Year Stretch & Challenge I do We do Test I do We do You do Do Now

2. SciDoc Keywords Learning Objectives Keywords Gravitational Potential Energy Height Metres Joules Mass State the types of object that have gravitational potential energy. Recall the equation for GPE. Calculate gravitational potential energies using the equation. I do We do Test I do We do You do Do Now

3. SciDoc Gravitational field strength Gravitational field strength The greater the height on an object above the ground, the greater the GPE it will have. The stronger the gravitational field strength, again the greater the GPE. On Earth, the gravitational field strength is 9.8 N/kg. Stretch: What would happen to the gravitational field strength the further away we went from Earth? I do We do Test I do We do You do LO:

4. SciDoc Equation for gravitational potential energy Equation for gravitational potential energy ??= ? ? ? Stretch: Rearrange the equation to give equations for mass, gravitational field strength and height. Gravitational potential energy, ?? in joules (J) Mass, ? in kilograms (kg) Gravitational field strength, ? in newtons per kilogram (N/kg) Height above the ground, in metres (m) I do We do Test I do We do You do LO:

5. SciDoc Rearranged equations Rearranged equations Stretch: Dr. Edmunds drops his iPad from a height of 2m. If the initial GPE is 3.92 J, what is mass of the iPad? ?? ? = g g x ? ?? m m x ? h = I do We do Test I do We do You do LO:
