# Lesson Plan: Applications of Newton’s Second Law: Horizontal Pulley Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve problems on the motion of two bodies connected by a string passing over a smooth pulley, where one is on a horizontal table.

#### Objectives

Students will be able to

• find missing forces and masses in systems involving a body on a horizontal plane connected to another body suspended below a smooth pulley,
• use Newton’s second law of motion and the equations of motion to solve horizontal plane and pulley problems,
• find the force exerted on the pulley connecting a mass on a horizontal surface to a vertically hanging mass.

#### Prerequisites

Students should already be familiar with

• resolving forces for systems on a smooth or rough horizontal plane,
• the equations of motion,
• Newton’s second law of motion.

#### Exclusions

Students will not cover

• systems involving an inclined plane.
