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 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 filament lamp, a power station, 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 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. 
Solve problems using mathematical relations learnt in this unit.
