1 Demonstrate understanding involves showing an awareness of how simple facets of phenomena, concepts, or principles relate to a given situation. Demonstrate indepth understanding involves giving explanations for phenomena, concepts, or principles that relate to a given situation. Demonstrate comprehensive understanding involves connecting concepts or principles that relate to a given situation. 2 Mechanical systems include mathematical solutions and/or written descriptions. Written descriptions may include graphs or diagrams. 3 Assessment is limited to a selection from the following: Translational Motion Centre of mass (1 and 2 dimensions); conservation of momentum and impulse (2 dimensions only). Circular Motion and Gravity Velocity and acceleration of, and resultant force on, objects moving in a circle under the influence of 2 or more forces, Newton’s Law of gravitation, satellite motion. Rotating Systems Rotational motion with constant angular acceleration; torque; rotational inertia; conservation of angular momentum; conservation of energy. Oscillating Systems The conditions for Simple Harmonic Motion, angular frequency, variation of displacement, velocity and acceleration with time, phasor diagrams, reference circles, damped and driven systems, resonance, conservation of energy.
