Lesson Plan: Resultant Motion and Force Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to show that motion in directions that are at right angles to each other can be represented by motion in one direction.


Students will be able to

  • calculate perpendicular components of a vector representing a displacement, velocity, acceleration, or force,
  • calculate the resultant of multiple vectors representing displacements, velocities, accelerations, or forces.


Students should already be familiar with

  • the sine, cosine, and tangent of an angle in a right triangle,
  • the Pythagorean theorem,
  • kinematic SUVAT equations.


Students will not cover

  • 3D vectors.
