Now, let's begin work on the basic **kinematic** quantities,
which we will use to describe motion.

When we measure motion, the most important quantities are

- position and displacement
- velocity
- acceleration
- time

First, let's discuss position, displacement, and velocity.

Next, let's introduce acceleration.

To check our understanding of these terms, let's analyze the motion of a fastball.
