Lecture 2 (Energy) - Understand and identify different types of systems - Explain the concepts of energy, work, potential energy and kinetic energy supported by the appropriate formulae. - Explain the Law of Conservation of Energy. - Use the concepts of energy transformations and power to solve applied problems. - Manipulate equations using basic algebra, including transposing, substituting and simplifying formulae. Week 3 (Fluids and Graphing) - Understand the concept of density. - Explain the concept of pressure particularly within the context of fluids and its importance in the human system. - Describe the processes of sinking and floating as encapsulated in - Archimedes principle. - Understand and apply the concept of continuity. -Describe qualitatively the factors that determine the movement of blood in a blood vessel (Poiseullie's law) and solve problems involving these factors. -Explain the process of osmosis in terms of chemical and pressure potentials as applied to soft and hard cells. - Levers Week 4 (Electricity) - Describe the forces that exist between electric charges - Calculate the work done by objects moving in different types of fields. - Explain the concept of potential and potential difference, and hence define the Volt as the work done per unit charge Identify the process of charge separation as the origin of electrical potential difference. - Undertake calculations involving these concepts
