How can I make bodyvelocity increase in the direction of the look vector?

Firstly, you will need to to add BodyVelocity to the object you want to move. Then We need the Parent the BodyVelocity to your chosen object. This script is a example of how to make the Player's Torso move to the direction of where the character is looking which mean's that you'll need to adjust it to your fitting.

local Player = game.Players.LocalPlayer--Gets the LocalPlayer
Player.CharacterAdded:wait()--Wait for the Character to load
local Char = Player.Character--Variable referencing to the Player's Character for quick access. 

local Body = Instance.new("BodyVelocity",Char.Torso) --Create BodyVelocity and Parents it to Player's Torso.
Body.maxForce = Vector3.new(1e7,1e7,1e7)--The the Maximum amount of force the BodyVelocity can use.
Body.velocity = Player.Character.Head.CFrame.lookVector*40*2--Change the Body's Velocity to the way the Character's Head if facing.
