How could I make my controller better and more normal?

I'm trying to make a mini game and the player is replaced with a cube, I need to be able to move the cube more efficiently. Any and all answers are appreciated.

Object = workspace.PlayerCube

game:GetService("UserInputService").InputBegan:connect(function(Input)
    if
        Input.KeyCode == Enum.KeyCode.D then
        Object.BodyForce.Force = Vector3.new(7,196.2,0) * Object:GetMass()
    end
    if
        Input.KeyCode == Enum.KeyCode.S then
        Object.BodyForce.Force = Vector3.new(0,196.2,7) * Object:GetMass()
    end
end)

I used 196.2 in the Y axis to get rid of the downward force of gravity but then it gets tricky for me to script the rest.
