Is Work Done? — Decision Tree for Common Scenarios

Is Work Done? — Decision Tree for Common Scenarios

The map in words

  • Apply Force on Body
    • Is there any Displacement?
      • No s = 0: W = 0\nNo Work Done
      • Yes s is not zero: Angle between Force\nand Displacement?
        • Theta = 0 degrees: W = F x s\nMaximum Positive Work
          • Example: Free fall\ngravity aids motion
        • Theta = 90 degrees: W = 0\nZero Work Done
          • Example: Coolie on platform\nload weight perpendicular
        • 0 less than Theta less than 90: W = Fs cos Theta\nPositive Work
          • Example: Pulling cart\nat an angle
        • 90 less than Theta up to 180: W = Fs cos Theta\nNegative Work
          • Example: Friction opposes\nmotion of sliding block
