Do you know your x-t graphs?

x t Slowing Down (in the positive direction) Negative Acceleration 

x t Constant Speed Constant + Velocity

x t Slowing Down (in the – direction) Positive Acceleration

x t Constant Speed Constant - Velocity

x t Speeding Up (in the + direction) Positive Acceleration

x t Speeding Up (in the - direction) Negative Acceleration 

x t At Rest (stopped … no motion)

x t Is this object ever at rest??? YES!!! When you change directions, you must come to a stop (for an instant)
