In a pumped-storage hydroelectric power station, water is pumped to an upper reservoir, transferring energy into a gravitational potential store. However, some energy is wasted due to friction and turbulence in the pipes.
State what happens to this wasted energy.
82 exam-style questions on Edexcel GCSE Physics 3.1 Energy stores and calculations, covering 3.1.1 Gravitational potential energy, 3.1.2 Kinetic energy, and 3.1.3 Energy transfers and conservation of energy. Each one has a worked solution and a mark scheme showing where the marks go.
