Lesson Plan: The Equilibrium of a Body on a Rough Horizontal Plane Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve problems involving the equilibrium of a body on a rough horizontal plane.


Students will be able to

  • solve equilibrium problems on rough horizontal planes,
  • find the coefficient of friction between an object and a rough horizontal plane,
  • find the angle of friction in a given model,
  • find missing values in a system involving a rough horizontal plane and smooth pulleys.


Students should already be familiar with

  • the equilibrium of a body on a smooth horizontal plane,
  • finding resultant forces.


Students will not cover

  • the equilibrium of a body on an inclined rough plane.
