Topics in Work, Energy and power

1

Work and Its Measurement

  • Work is done only when a body is displaced under the influence of an applied force
  • If there is no displacement, no work is done (e.g., pushing a wall, holding a bucket)
  • Work is a scalar quantity with magnitude but no direction
2

Power and Its Units

  • Power is the rate of doing work or energy transfer per unit time
  • Greater power means same work is done in less time
  • Power depends on both work done and time taken
3

Energy and Its Forms

  • Energy is the capacity to do work
  • Energy can exist in various forms but total energy is conserved
  • Mechanical energy consists of kinetic and potential energy
4

Kinetic Energy

  • Energy possessed by a body due to its motion
  • Depends on mass and square of velocity
  • Doubling velocity increases KE by four times
