Unit 2: Introduction to Newton's Laws

Ever since Isaac Newton's publication of The Principia in 1686, humans have looked at the universe as a big machine.  In this unit, after we go through some information about projectiles, you will learn the rules that govern the machine.  Exciting stuff! 

Suggested timeframe: 4 weeks

Big Ideas:
•Physical systems (that may have internal structure) and objects (that do not have internal structure) can be characterized by certain properties.
•Interactions (between objects in systems or between systems themselves) can be explained using an idea called a field.
•The concept of force can be used to describe the interactions between objects in systems or between systems themselves.
•Systems can change due to interactions with other systems.
