Physics Thrusters [Need Help] [Beginner]

Hi, I am trying to use the Physics Thrusters for the first time and I can’t really find anything on them. Not sure if I’m just terrible at looking or if theres just little info on them and how to properly use them. Currently I am trying to make my Spaceship thruster forward. I have a Thrust Strength Float variable and my ship forward axis event. I am then multiplying the axis value by 1000 and plugging it in to the thrust strength with the target as the Physics thruster. Any clue how to actually make this work? Thank you.
