# Lesson Plan: Momentum Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula for momentum, 𝘱 = 𝑚𝑣, to calculate the momentum of objects and calculate changes in an object’s momentum.

#### Objectives

Students will be able to

• use the formula in all combinations,
• demonstrate that differences in velocity imply differences in momentum,
• demonstrate that differences in mass imply differences in momentum,
• explain that momenta of multiple objects can be summed to find their total momentum,
• identify momentum as a vector quantity,
• demonstrate that momenta in opposite directions have opposite signs when summed.

#### Prerequisites

Students should already be familiar with

• velocity.

#### Exclusions

Students will not cover

• two-dimensional motion,
• exchanges of momentum between objects (the summation of the momenta of two objects is included, while the transfer of this combined momentum between said objects is not),
• forces.
