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"
