How can calculus help us in physics?

Today, for those who haven't completed a calculus course yet, we'll talk about the basics of derivatives and integrals, and see how this would help us with kinematics problems.  You'll be grouped heterogeneously in small groups to learn about derivatives and integrals are.  We'll look particularly at position vs. time graphs and velocity vs. time graphs.  

Homework:   If you have issues understanding how calculus applies to kinematics, rewatch some videos from the past week or read the textbook Chapter 2.  Watch the video below on rotational kinematic variables.  Take notes while you watch!  Understanding these concepts are EXTREMELY IMPORTANT in being successful in the rest of this unit, so take the time to rewind and rewatch as needed.  (When Mr. Fullerton derives centripetal acceleration in minute 13, he talks about unit vectors.  "I-hat" is a unit vector magnitude 1 in the x direction.  "J-hat" is a unit vector magnitude 1 in the y direction.  Unit vectors are really just multipliers which turn scalar magnitudes into vectors with direction.)
