OCR AAQ in Applied Science: P2: Motion

Course: OCR Level 3 Alternative Academic Qualification Cambridge Advanced Nationals in Applied Science. 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
