Physics disabled when i added motion

I’m making basic motion and look inputs for my pawn (which is just a sphere). Although I did add physics to my Pawn’s Static mesh, when I added the movment BP the physics is disabled and I can now go through objects in the world and dont have gravity. And when I hit play and move around I can still see the sphere of my pawn in the game. How can I remove this? and is it there because the movement is controlled by the player controller not the pawn itself? although the BP is in the Pawn File?
