Chapter 5: Projectile Motion

Pace: 7 class periods
Checkpoint: 28 October 

Big Idea
Forces have magnitude and direction.The net force on an object is the sum of all the forces acting on the object. Objects change their speed and/or direction only when a net force is applied. If the net force on an object is zero, there is no change in motion (Newton’s First Law). 


Standards
3.2A Identify the magnitude and direction of everyday forces (iwind, tension in ropes, pushes and pulls, weight)
P3.2d Calculate all the forces on an object on an inclined plane and describe the object’s motion based on the forces using free-body diagrams.
P3.4e Solve problems involving force, mass, and acceleration in two-dimensional projectile motion restricted to an initial horizontal velocity with no initial vertical velocity (e.g., a ball rolling off a table). 


Ch 5 Pretest 
If you score a 90% or above on this pretest on your first attempt most of your work for this section will be substituted for a more challenging assignment that you will identify with your teacher.  The pretest is not open internet or buddy or book.  This pretest will be timed and may only be completed in class the day this chapter is assigned.
