What is kinematics
branch of mechanics that deals with how far, how fast, and how consistent a body moves.
looks at distances, speeds, & accelerations
400

Describe and compare the dot diagrams. 
The first one is moving at a constant velocity. The second one is moving at a constant velocity but slower and the third dot diagram is accelerating.

Describe what is happening in this dot diagram by interval
moving with a constant speed in the first time interval. then abruptly decelerates to a stop. remains at rest for sometime and then moves with a constant speed, slower than the first speed.
