Movement smoother?

Hi!
When i touch a bottom, my player starts to to move at the speed of 30. = Player.x += 30. Is there anyway to make that movement smoother? Becuase its looks a bit laggy.

My friend told me that he belived that you could write some code that says that “Player.update bla bla bla…” That the player should be updateted more often or something like that.
