- 1. 20/04/16 P3 Energy, Work & PowerP3 Energy, Work & Power Syllabus statementsSyllabus statements Statements from Cambridge IGCSE Combined Science syllabus 0653 (for exams in 2016 – 2018)
- 2. 3.1 Energy3.1 Energy 1. Know that energy & work are measured in joules (J), and power in watts (W). 2. Demonstrate understanding that an object may have energy due to its motion (kinetic) or its position (potential), and that energy may be transferred and stored. 3. Recall and use the expressions K.E. = ½ mv2 and P.E. = mgh
- 3. 3.1 Energy3.1 Energy 4. Give and identify examples of energy in different forms, including kinetic, gravitational, chemical, strain, nuclear, thermal (heat), electrical, light and sound. 5. Give and identify examples of the conversion of energy from one form to another, and of its transfer from one place to another. 6. Apply the principle of energy conservation to simple examples.
- 4. 3.2 Energy Resources3.2 Energy Resources 1. Distinguish between renewable and non- renewable sources of energy. 2. Know that the Sun is the source of energy for all our energy resources except geothermal and nuclear.
- 5. 3.2 Energy Resources3.2 Energy Resources 3. Describe how electricity or other useful forms of energy may be obtained from: • chemical energy stored in fuel • water (including energy stored in waves, in tides, & in water behind hydroelectric dams) • geothermal resources • heat and light from the Sun (solar cells & panels) • wind.
- 6. 3.2 Energy Resources3.2 Energy Resources 4. Give advantages & disadvantages of each method in terms of reliability, scale and environmental impact. 5. Demonstrate a qualitative understanding of efficiency. 6. Recall and use the equation:
- 7. 3.3 Work3.3 Work 1. Relate (without calculation) work done to the magnitude of a force and the distance moved. 2. Describe energy changes in terms of work done. 3. Recall and use W = F × d
- 8. 3.4 Power3.4 Power 1. Relate (without calculation) power to work done and time taken, using appropriate examples. 2. Recall and use the equation P = E / t in simple systems.
