In this lesson, students will explore the relationships of the different forces on an object such as weight, normal force, parallel force, and friction.

• Students will explore the force due to weight and the normal force.
• Students will determine the relationship between weight, normal and the force parallel to an incline.
• Students will explore friction force and its relationship to weight, normal, and the parallel force.

• force
• weight
• normal force
• parallel force
• force of friction

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.
