moving an actor (what is the best way)???

bgapps

What is the best way to move an actor? I know there are multiple ways of doing this, like interpolating and acceleration. I want the actor to stop if the left or right button is NOT pressed. I tried accelerate, but once I released the button it still moves slightly.
thanks

turn friction to 100
and restitution to 0

and put max speed to 500

it should run smoothly
