Momentum is usually referred to as velocity on this site...I guess to most people they're similar enough...For momentum, instead of changing your x and y positions, you change the change of your x and y positions. This will require a minimum of one variable (for only one axis) or two variables (for both x and y).

Scripts usually look like this:

when gf clicked
set x to (start x)
set y to (start y)
set [xvel v] to (0)
set [yvel v] to (0)
forever
  if <[right arrow v] key pressed?>
    change [xvel v] by (.2)
  end
  if <[left arrow v] key pressed?>
    change [xvel v] by (-.2)
  end
  if <[up arrow v] key pressed?>
    change [yvel v] by (.2)
  end
  if <[down arrow v] key pressed?>
    change [yvel v] by (-.2)
  end
  set [xvel v] to ((xvel) * (.95))
  set [yvel v] to ((yvel) * (.95))
  change x by (xvel)
  change y by (yvel)
end

Hopefully this is the effect you were talking about.

Yes! it is! Thank you!
