I obtained the result when I measured the angle between the launching starting point and the apex of the trajectory of the bottle rocket. I was 30 metres away of the starting point whenmy friend started pumping to measure this angle.
Could you please help me find experimental error in bottle rocket experiment that could have affected my results. The experiment is where a bottle gets filled with water, a third of their volume and then they get pressurized to fly in the air.
So could you please find me experimental errors...
