Unit 6 “WORK AND ENERGY”, covering learning objectives such as:
1. define work and its SI unit; work = force × distance moved in the direction of force.
2. calculate work done using the equation: work = force × distance.
3. define kinetic energy and potential energy. State unit of energy.
4. prove that Kinetic Energy, Eₖ = ½ mv² and potential energy Eₚₑ = mgh and solve problems using these equations.
5. list the different forms of energy with examples.
6. describe the processes by which energy is converted from one form to another – reference to fossil fuel energy – hydroelectric generation – solar energy – geothermal energy and biomass energy.
7. state mass energy equation E = mc² and solve problems using it.
8. describe the process of electricity generation by drawing a block diagram of a power station.
9. process from fossil fuel input to electricity output.
10. list environmental issues associated with power generation.
11. differentiate energy sources as non renewable and renewable energy sources with examples of each.
12. explain by drawing energy flow diagrams through steady state systems such as Filament lamp, a power station, a vehicle traveling at a constant speed on a level road.
13. define efficiency of a working system and calculate the efficiency of an energy conversion using the formula: efficiency = energy converted into the required form / total energy input.
14. explain why a system cannot have an efficiency of 100%.
15. define power and calculate power from the formula Power = work done / time taken.
16. define the unit of power “watt” and its conversion with horse power.
17. solve problems using mathematical relations learnt in this unit.
