You should make sure you understand that moments have direction. You need to find a direction for the force and also look at the distance in perpendicular direction.

For moments in paper 2, you must make sure how to define a moment. Moment is a turning effect of a force. Also, know the equation that relates moments. For example, M = F x D. This is how you would need to define the moment in a question that asks for a definition. Also, make sure that spelling and grammar is correct when defining it or using any relevant terminology regarding moments.

For Moments in Paper 2, it's crucial to use specific terminology related to physics and engineering. Terms you should consider incorporating include:

  1. Torque
  2. Pivot Point
  3. Lever Arm
  4. Clockwise and Anti-clockwise Moments
  5. Equilibrium
  6. Net Moment
  7. Center of Mass
  8. Angular Displacement
  9. Angular Velocity
  10. Angular Acceleration

Using these terms accurately will demonstrate a strong understanding of the topic and contribute to a more precise and credible paper.

  • the turning effect a force has around a point is a moment,
  • A force must act upon an object so that the body would begin to turn,
  • Moment = Force X Perpendicular Distance,
  • For aan object to be in equilibrium the total moments must be equal,
  • The weight of an object operates through its centre of mass
