1/21/2009 P30 Unit A – Momentum and Impulse POS Checklist The following is a list of ideas and concepts you need to know to be able to pass the Unit A test. They are taken from the Alberta Learning Program of Studies. Check off each idea as you study it at home. General Outcome: explain how momentum is conserved when objects interact in an isolated system. Knowledge Outcomes: I can: define momentum as a vector quantity equal to the product of the mass and the velocity of an object explain, quantitatively, the concepts of impulse and change in momentum, using Newton’s laws of motion. explain, qualitatively, that momentum is conserved in an isolated system. explain, quantitatively, that momentum is conserved in one- and two-dimensional interactions in an isolated system define, compare and contrast elastic and inelastic collisions, using quantitative examples, in terms of conservation of kinetic energy. Performing and Recording Outcomes: I can: perform an experiment to demonstrate the conservation of linear momentum, using available technologies. collect information from various print and electronic sources to explain the use of momentum and impulse concepts Analyzing and Interpreting Outcomes: I can: analyze graphs that illustrate the relationship between force and time during a collision analyze, quantitatively, one- and two-dimensional interactions, using given data or by manipulating objects or computer simulations Communication and Teamwork: I can: use appropriate International System of Units (SI) notation, fundamental and derived units and significant digits use appropriate numeric, symbolic, graphical and linguistic modes of representation to communicate ideas, plans and results use delta notation correctly when describing changes in quantities LD Industries
