Lesson 2: Free Body Diagrams
Duration of Days: 2
Lesson Objective
Students will be able to (I can) learn how to draw free body diagrams. They will demonstrate knowledge of push, pull, and acceleration forces.
What is a free body diagram?
Are there specific forces that are common to most free body diagrams?
Do we apply a vector for movement in a free body diagram?
What direction does the normal force always point?

GS3: Modeling
Students can construct and use models to represent and analyze phenomena and systems.
Basic math skills for calculating net forces.
This lesson is a vital part of force summation and calculation. Drawing free body diagrams allows students to identify all forces acting on an object and determine what calculations can be done to determine the magnitude of each force.
DOK: 2-3
All of the examples they use to create FB diagrams come from real world situations of single objects and their movement or lack there of.
All objects exhibit all forces at all times.
That gravity is not ever present.
When calculating the misuse of graphing coordinates.

Students will be assessed on their ability to correctly draw a free body diagram for a variety of described motions of various objects. Formative assessment
Practice problems either online or on paper. Preferably paper so they can be drawn out by hand.
Calculators
Laptops
Rulers if necessary.
