This tutorial will show you how to add velocity to moving objects. First make a VELOCITY VARIABLE

<{  VELOCITY  }>

1. When you want the object to move, in this case we will do forward, set a control for moving forward (up arrow). Build script: If Up Arrow pressed change VELOCITY by (whatever # you decide)
2. Next build script so that when the up arrow is released the object is still moving, but is slowing down. 
Script: (If up arrow key is not pressed) and if velocity is  VELOCITY >0, change VELOCITY by (depending on how fast you want the object to slow down)
3. Create Script: Move (VELOCITY/10) Steps

This can be applied even if you want the object to move in reverse, just change the control and repeat the process.
