2. Chapter 4-Motion with a changing velocity
2.1. 2 Essential relationships
2.1.1. Change in velocity over a period of time= acceleration x elapsed time
2.1.2. Average Velocity=1/2(final+initial velocity)x change in time
2.2. Other Relationships
2.2.1. -Velocity with a +Acceleration=Decreasing Speed
2.2.2. +Acceleration=Increasing velocity
2.2.3. Increase in speed=positive velocity and acceleration
