Topic Area P2: Motion

• How energy is stored
• How energy is transferred via energy carriers or pathways
• How diagrams can be used to represent energy transfers
• How to draw scale Sankey diagrams
• Know the definition of work done by a force
• Know the unit of work done
• Use of the equations:
  • Work done (J) = force (N) × displacement (m)
  • Work done (J) = force (N) × displacement (m) × cosθ
  • Power (W) = work done (J) x time (s)
  • Efficiency = useful energy transferred /total energy transferred
  • SUVAT equations
  • Kinetic energy equation
  • Gravitational potential energy equation
  • Elastic potential energy equation
• Determine the work done on a spring from a graph
• Apply conservation of energy to examples involving gravitational potential
• Law of conservation of energy
• energy, elastic potential energy, and kinetic energy
• Newton’s first and third laws of motion
• Newton’s second law of motion for constant mass
• Use of Newton’s three laws of motion including how to use free-body force diagrams to solve problems
• The vector–scalar distinction as it applies to displacement and distance, velocity and speed
• Use of apparatus, techniques and procedures to accurately determine the
  acceleration of free fall using trapdoor and electromagnet arrangement; light gates and timer
