For Weight Calculations;
Remember to show ALL your working out useing FIFA;
  • Formula
  • Insert Values*
  • Fiddle (rearrange if needed)
  • Answer (with units)
EXAMPLES ARE ON THE SAME SHEET IN THE CONTENT LIBRARY.  
USE THIS TO CHECK YOU ARE DOING IT CORRECTLY

* When inserting values, check if you need to convert any units;
  • mass must be in kg (not g) e.g. 300g = 0.3 kg
    • when converting g to kg, divide by 1000
  • Weight must be in N (not kN) e.g. 4.5 kN = 4500 N
    • when converting kN to N, multiply by 1000
For the Balanced forces sheet;
  • To calculate an overall force for forces acting in opposite directions you find the difference the forces (subtract one from the other) - 
  • (If they are in the same direction you just add them up)
  • An overall (Resultant) force will always act in the direction of the larger force.
  • Use your handouts or the attached slides on the content library if you need help with the labels for the force diagrams for question 2
