Rocket launch simulator

I found that making the mass of the rocket 5kg and the thrust no more than 300 newtons resulted in my best outcome. Furthermore I found that making the thrust time higher and turning the drag off also helped my rocket get higher into the sky. This shows that every action has an equal and opposite reaction force to the object, which in this case is the rocket. Additionally is proves that the more mass there is the less the object will accelerate. Overall my results clearly show that in order for the rocket to be successful I must follow the newtons third law which which clearly states that an action will have and equal or stronger action in return.
