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 you will learn the rules that govern the machine.  Exciting stuff! 

Suggested timeframe: 2 weeks

Big Ideas:
1. The trajectory of a particle in a uniform gravitational field is parabolic. 
2. Force equals mass times acceleration.
3. Newton's Laws of Motion are used to analyze how force affects the state of motion of an object.
4. Motion is always measured relative to an arbitrary frame of reference.
5. All uniform circular motion requires a centripetal force.
