Many things do not move with uniform motion.  Today we will start exploring how graphs of uniform motion and non-uniform motion might compare.  You have been used to plotting position-time graphs, but today we will see what graphs of velocity-time graphs might look like for non-uniform motion.

Things you should be able to do after today:

  • Draw a position-time graph and a velocity-time graph from the same data
  • Describe how a position-time graph looks when a velocity-time graph has a positive slope
  • Desrcibe how a position-time graph looks when the velocity-time graph has a negative slope

When an object is not traveling with uniform motion (or traveling with non-uniform motion), it means that its velocity is not staying constant.  If the velocity is changing at a constante rate, we call this acceleration.  Today, we will begin looking at acceleration, and focus on what the sign on acceleration means and how it relates to the sign on the change in velocity

Things you should know after today:

  • how acceleration is related to uniform motion
  • how to determine if acceleration is positive or negative
  • how acceleration is related to
  • how acceleration is related to speed and velocity
  • the difference in our use of the words "acceleration" and "accelerating"
