SLOs Of 9th Class Physics Notes Of Work And Energy


After  studying this chapter of 9th class physics students will be able to: 

  • Define work and its SI unit. 


  • Calculate work done using the equation Work = force x distance moved in the direction of the force. 


  • Define energy, kinetic energy, and potential energy. 


  • State unit of energy. 


  • Prove that kinetic energy and potential energy. 


  • Solve problems using these equations. 


  • List the different forms of energy with examples. 


  • Describe the processes by which energy is converted from one form to another with reference to


  • Fossil fuel energy


  • Hydroelectric generation


  • Solar energy


  • Nuclear energy


  • Geothermal energy


  • Wind energy


  • Biomass energy


  • State mass-energy equation and solve problems using it. Describe the process of electricity generation by drawing a block diagram of the process from fossil fuel input to electricity output. 


  • List the environmental issues associated with power generation. 


  • Explain by drawing energy flow diagrams through steady-state systems such as a filament lamp, a power station, or a vehicle travelling at a constant speed on a level road. Differentiate energy sources as non-renewable and renewable energy sources with examples of each. 


  • Define the efficiency of a working system and calculate the efficiency of energy conversion using the formula:


  • efficiency = energy output converted into the required form / total energy input


  • explain why a system cannot have an efficiency of 100%. Define power and calculate power from the formula: Power = work done / time taken


  • Define the unit of power “watt” in SI and its conversion with horsepower.
