About the Lesson

Students will be exploring the relationships of the different forces on an object such as weight, normal force, parallel force, and friction.
As a result, students will:

  • Be able to determine weight.
  • Understand the relationship between weight and normal force on a surface.
  • Be able to determine the relationship between weight, normal, and parallel forces.
  • Determine the effect of friction on the system.
