Chapter 2: Mechanical Equilibrium 

Pace: 5 days
Checkpoint:   25 September

Big Ideas

Standards
P3.1 Basic Forces in Nature
Objects can interact with each other by “direct contact” (pushes or pulls, friction) or at a distance (gravity, electromagnetism, nuclear).

P3.2 Net Forces 
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). 

P3.1A Identify the force(s) acting between objects in “direct contact” or at a distance.
P3.2A Identify the magnitude and direction of everyday forces (e.g., wind, tension in ropes, pushes and pulls, weight). 
P3.2B  Compare work done in different situations.
P3.2C  Calculate the net force acting on an object.

2 Pretest and Student Differentiation

If you score a 90% or above on this pretest on your first attempt you will not need to complete any of the practice for this unit and an accelerated assignment will be provided.  The pretest is not open internet or buddy or book.  This pretest will be timed and may only be completed in class. 
Student Examples:
no student tested out of this unit

DAY 1 - 19 Sept
2.1 & 2.3
What is a Force?

Standard Practiced:
P3.1A
P3.2A
P3.2C

Big Ideas:
2.1: A force is needed to change an object's state of motion.
2.3: For an object at rest on a horizontal surface, the support force must equal the object's weight.
