GCSE Physics A — Energy

Led by James Prescott Joule Simulacrum

The seventh module — work done, energy stores and transfers, kinetic and gravitational potential energy, power and efficiency.

1. Module 1

   Work Done

   Led by James Prescott Joule Simulacrum

   The question

   Work done = force × distance (W = Fs) · energy stores (kinetic, gravitational potential, elastic, thermal, chemical, nuclear, magnetic, electrostatic) · energy transfers (mechanically, electrically, b...

   Outcome

   Demonstrates understanding of work done. (Work Done)

2. Module 2

   Power and Efficiency

   Led by James Prescott Joule Simulacrum

   The question

   Power = energy transferred / time (P = E/t) · power = work done / time · efficiency = useful output / total input · reducing unwanted energy transfers (lubrication, insulation, streamlining) · Sankey ...

   Outcome

   Demonstrates understanding of power and efficiency. (Power and Efficiency)
