Science Buddies: "Ask an Expert"

What can the aim and hypothesis for this question be in a experimental report?? I'm using different balls with different masses and drop them at the same time to see and record time. What are different hypothesises and aims for this experiment?

Welcome to the Forum, RobinHoodCookies. For your hypothesis you could try "The mass of an object does not affect the falling speed." Or the opposite. Next do the experiment and see if the hypothesis is true or false. Good luck!
